### MAA Invited Address

#### Uncertainty: The Mathematics of What we Don’t Know

*9:00 a.m. - 9:50 a.m., Duke Energy Convention Center, Grand Ballroom A*

**Ami Radunskaya**, *Pomona College*

Over the past few centuries, the theory of probability has been developed to quantify possibilities and to help us make decisions with incomplete knowledge. More recently, this theory has been refined to include predictions based on randomly perturbed dynamical systems, as well as providing a measure of our belief in future events based on observed data. As mathematicians, we like precision, patterns, predictions. As human beings we want to make wise, informed decisions. In this talk I will explore three questions: how can we quantify the uncertainty in our predictions, how do we make decisions in the face of uncertainty, and when is a bit of uncertainty helpful … or fun?

##### Learning in Games

*10:00 a.m. - 10:50 a.m., Duke Energy Convention Center, Grand Ballroom A*

**Éva Tardos**, *Cornell University*

Selfish behavior can often lead to suboptimal outcome for all participants, a phenomenon illustrated by many classical examples in game theory. Over the last decade we have studied Nash equilibria of games, and developed good understanding how to quantify the impact of strategic user behavior on overall performance in many games (including traffic routing as well as online auctions). In this talk we will focus on games where players use a form of learning that helps them adapt to the environment. We ask if the quantitative guarantees obtained for Nash equilibria extend to such out of equilibrium game play, or even more broadly, when the game or the population of players is dynamically changing and where participants have to adapt to the dynamic environment.

### Invited Address

#### Earle Raymond Hedrick Lecture Series

##### Complex Dynamics and Elliptic Curves, Lecture I

*11:00 a.m. - 11:50 a.m., Duke Energy Convention Center, Grand Ballroom A*

**Laura DeMarco**, *Northwestern University*

In a series of three talks, I will present connections between recent research in dynamical systems and the classical theory of elliptic curves and rational points. On the dynamical side -- specifically in the study of iteration of rational functions (Julia sets, bifurcations, the Mandelbrot set) -- the first connections were observed about 100 years ago. On the arithmetic side, it was probably the 1960s when dynamical ideas were first used as tools to understand the arithmetic geometry of elliptic curves and higher-dimensional varieties. My goal is to provide an overview of how these relationships developed and where they have brought us today. The three lectures will be independent.

### Poster Session

### Workshop

#### What’s the Story? Research Presentations for an Undergraduate Audience

*1:30 p.m. – 2:50 p.m., Duke Energy Convention Center, Room 201*

Presenting recent and ongoing research to undergraduate students is fun and rewarding, but frequently challenging. The gory details of mathematical results often require a great deal of specific jargon and background knowledge. Nonetheless, the big idea-the “story”-can almost always be presented at a variety of levels. This workshop is designed to help graduate students formulate a presentation on their research that is appropriate for an audience of undergraduate students, something many colleges and universities require as part of a job interview. Moreover, the ability to communicate complex mathematical ideas is a valued trait in any context. As such, this session aims to develop a framework for creating an engaging and accessible presentation for undergraduates. Graduate students who will be going on the job market in the fall may find this workshop especially useful.

### Invited Paper Session

#### The Mathematics of Uncertainty

*10:10 a.m. - 12:00 p.m., Duke Energy Convention Center, Room 200*

We encounter uncertainty everywhere, at all levels of consciousness, in all of our endeavors. Even things of which we are certain: the sun rises tomorrow, our existence has a finite time span, are subject to imprecision. How has mathematics helped us understand uncertainty and unpredictability?

In this session we present mathematics that guides decisions under incomplete information or cognitive limitations.

### Invited Address

#### Earle Raymond Hedrick Lecture Series

##### Complex Dynamics and Elliptic Curves, Lecture II

*10:20 a.m. - 11:10 p.m., Duke Energy Convention Center, Grand Ballroom A*

**Laura DeMarco**, *Northwestern University*

In a series of three talks, I will present connections between recent research in dynamical systems and the classical theory of elliptic curves and rational points. On the dynamical side -- specifically in the study of iteration of rational functions (Julia sets, bifurcations, the Mandelbrot set) -- the first connections were observed about 100 years ago. On the arithmetic side, it was probably the 1960s when dynamical ideas were first used as tools to understand the arithmetic geometry of elliptic curves and higher-dimensional varieties. My goal is to provide an overview of how these relationships developed and where they have brought us today. The three lectures will be independent.

### Invited Address

#### MAA Invited Address

##### Solving Algebraic Equations

*11:20 a.m. - 12:10 p.m., Duke Energy Convention Center, Grand Ballroom A*

**Irena Swanson**, *Reed College*

Abel and Ruffini, and later Galois showed that general polynomials of degree five or higher are not solvable with the usual arithmetic operations. Nevertheless, algebra offers powerful methods for solving many equations and for determining the structure of solutions even when the solutions themselves cannot be found. In this talk I will cover some classical and more recent methods, including Hilbert's Nullstellensatz and Gr\"obner bases. A running theme will be computational complexity, and the talk will end with more recent results in commutative algebra.

### Other Mathematical Session

#### AWM-MAA Etta Zuber Falconer Lecture

##### Dance of the Astonished Topologist ... or How I Left Squares and Hexes for Math

*1:30 p.m. - 2:20 p.m., Duke Energy Convention Center, Grand Ballroom A*

**Tara Holm**, *Cornell University*

Topology is often called ``rubber sheet geometry" and is described as ``floppy" while geometry is more ``rigid". Symplectic geometry, the natural geometry of classical mechanics, is floppier than Riemannian geometry but more rigid than topology. I will give a friendly introduction to some geometric and algebraic techniques in topology, proving along the way that a topologist can turn her trousers inside out without taking them off. I will then give an overview of the floppy/rigid spectrum, motivated by many pictures and examples. I will conclude with a description how covering spaces have been useful in my own work in symplectic geometry, and how they can make square dancing more challenging.

### Town Hall Session

#### Quantitative Literacy and Social Justice

*3:00 p.m. - 4:20 p.m., Duke Energy Convention Center, Room 201*

At the 2019 Joint Mathematics Meetings, Dave Kung and Kira Hamman called for a need to teach mathematics and quantitative literacy with an eye toward social justice. As part of their presentation, they not only reiterated the importance of promoting quantitative literacy for social justice (and vice versa), but they also pushed the audience to consider diverse and potentially divisive issues ranging from who “receives” quantitative literacy on their campus to how students are positioned in mathematics classrooms. Their remarks accentuate that the relationship between quantitative literacy and social justice is complex, and that there is much for the mathematics and quantitative literacy communities to consider as we teach in an era of alternative facts, dueling memes, and politically charged classrooms.

SIGMAA-QL would like to invite all members of the mathematics community who are interested in issues of social justice as well as pathways toward a quantitatively literate society to a town hall discussion at MathFest 2019 to follow up on some of these questions. In particular at this session we hope to start a much needed conversation about the roles people of mathematics can play in promoting quantitative literacy for social justice (and vice versa). Issues we would like to discuss range from teaching mathematics for social justice, to the role of QL in charting a path towards a more just society, to the future of SIGMAA-QL as an ambassador of mathematicians interested in these issues. The organizers will come in with questions to initiate and facilitate the conversation, but we invite everyone interested to come and make their voices be heard.

### Invited Address

#### NAM David Harold Blackwell Lecture and National Association of Mathematicians Celebration

##### Dudeney's No Three-In-Line Problem: Problem, Solutions, Conditions, Progress, and Conjectures

*Friday, August 2, 4:00 p.m. - 5:45 p.m., Duke Energy Convention Center, Grand Ballroom A*

**Johnny L. Houston**, *Elizabeth City State University*

In 1917, Henry Dudeney, an Englishman who had done some intriguing things with mathematical puzzles and games, posed an interesting question for persons interested in discrete geometry. Let an n x n grid be given in the Euclidean plane for any natural number n, what is the maximum number of points that can be identified in the grid so that no three of these points are in the same line (no 3 colinear). For various natural numbers n, solutions have been discovered and certain conditions have been encountered.

The presenter discusses many of these solutions and conditions. For large natural numbers n, even for some n < 60, progress (or lack of progress) is being made slowly. By the Pigeon Hole Principle, the maximum number of such points that can exist is 2n. The problem of finding for which n this value is reached is known as the No-Three-In-Line Problem. Several conjectures exist. These conjectures and their motivations are discussed as well as some related problems. However, the No-Three-In-Line Problem is still an open problem.

The year 2019 is the centennial year of the honoree for which this lecture was named. The presenter will also discuss the life and contributions of David H. Blackwell.

Additionally, a light reception will follow the lecture to celebrate the National Association of Mathematicians's Golden anniversary.

### SIGMAA Activity

#### SIGMAA TASHM Business Meeting, Reception, Sliffe Award Winners Celebration, & Guest Lecture

##### Using History and Education Research to Shape the Calculus Curriculum

**David Bressoud**, *Conference Board of the Mathematical Sciences*

*6:00 p.m. - 7:30 p.m., Duke Energy Convention Center, Room 237 & 238*

This talk will explain how the historical development of calculus should be used to inform its instruction. The standard order of the four big ideas—limits then derivatives then integrals then series—is wrong both historically and pedagogically. In addition, the standard models for derivatives and integrals, slopes of tangents lines and areas under curves, erect obstacles in the path of many students. Drawing on history and recent research in undergraduate mathematics education, this talk will make the case for calculus introduced first as problems of accumulation (integration), then ratios of change (differentiation), then sequences of partial sums (series), and finally the algebra of inequalities (limits).

### SIGMAA Activity

#### SIGMAA SportsBusiness Meeting, Reception, and Guest Panel

##### Undergraduate Research in Mathematics & Sports

*6:00 p.m. - 7:30 p.m., Duke Energy Convention Center, Room 263*

#### MAA James R.C. Leitzel Lecture

##### What's at Stake in Rehumanizing Mathematics?

*9:00 a.m. - 9:50 a.m., Duke Energy Convention Center, Grand Ballroom A*

**Rochelle Gutiérrez**, *University of Illinois*

Embracing an "equity" standpoint that has been poorly defined (Gutiérrez, 2002) or constantly shifting (NCTM, 2008) has led to a state of “tinkering” as opposed to real change within mathematics (Gutiérrez, 2017). That is, our progress has often focused on, and ended with, closing the achievement gap or recruiting more diverse students into the mathematical sciences, but not trying to radically reimagine a mathematics that supports students, teachers, and members of society to thrive, something I refer to as Rehumanizing Mathematics. This approach begins with 1) acknowledging some of the dehumanizing experiences in mathematics for students, teachers, and citizens and 2) designing ways for people to be provided with windows and mirrors onto the world and relating to each other with dignity through mathematics. This focus on Rehumanizing Mathematics allows us to think differently about student misconceptions, teachers as identity workers, the histories of mathematics, our bodies in relation to mathematics, and why it is not just that diverse people need mathematics but mathematics needs diverse people. In this talk, I explore “what’s at stake” along two dimensions: 1) what it means for teachers, students, and society if we do not rehumanize mathematics and 2) what knowledge bases, sensibilities, and forms of risk taking it will require from us as mathematicians (and mathematics educators) if we commit deeply to rehumanizing mathematics.

### Invited Paper Session

#### Commutative Algebra

*9:00 a..m. - 11:50 a.m., Duke Energy Convention Center, Room 200*

Commutative algebra is a central discipline at the intersection of algebraic geometry, number theory, combinatorics, and so on. Many of the foundations were laid by Emmy Noether.

### Workshop

#### Get the Facts Out!

*9:00 a.m. - 10:20 a.m., Duke Energy Convention Center, Room 205*

Many math and science majors, despite an interest in teaching, do not pursue it as a career. Why? Research shows they (and their college faculty!) may hold beliefs such as: teacher pay is a lot less than other jobs, teachers can’t retire, and teachers are unhappy. **Get the Facts Out** resources can help counter these myths with data from empirical studies. This workshop will share these resources as well as offer assistance in creating materials to use in your own location.

**Get the Facts Out** is an NSF-funded collaborative effort between the Mathematical Association of America, the Colorado School of Mines, the American Physical Society, the American Chemical Society, and others.

### Invited Address

#### Earle Raymond Hedrick Lecture Series

##### Complex Dynamics and Elliptic Curves, Lecture III

*10:00 a.m. - 10:50 p.m., Duke Energy Convention Center, Grand Ballroom A*

**Laura DeMarco**, *Northwestern University*

In a series of three talks, I will present connections between recent research in dynamical systems and the classical theory of elliptic curves and rational points. On the dynamical side -- specifically in the study of iteration of rational functions (Julia sets, bifurcations, the Mandelbrot set) -- the first connections were observed about 100 years ago. On the arithmetic side, it was probably the 1960s when dynamical ideas were first used as tools to understand the arithmetic geometry of elliptic curves and higher-dimensional varieties. My goal is to provide an overview of how these relationships developed and where they have brought us today. The three lectures will be independent.

#### MAA Invited Address

##### A Vision of Multivariable Calculus

*11:00 a.m. - 11:50 a.m., Duke Energy Convention Center, Grand Ballroom A*

**Robert Ghrist**, *University of Pennsylvania*

This talk will address certain challenges in teaching multivariable calculus. Classical texts emphasize calculus in dimensions two or three, based on 19th and 20th century applications to physics. At present, many of our students are more motivated by data and systems in higher dimensions. How can a calculus course best adapt to these needs, without overwhelming students (or professors)? This talk will outline a plan for increasing both the dimension and sophistication of multivariable calculus instruction with the use of video. Topics covered will include the use of visualization, matrix algebra, and differential forms.

### Invited Address

#### Martin Gardner Lecture

##### Recreational Mathematics and Computer Science: Martin Gardner's Influence on Research

*Saturday, August 3, 2:00 p.m. - 2:50 p.m., Duke Energy Convention Center, Grand Ballroom A*

**Erik Demaine**, *Massachusetts Institute of Technology*

Martin Gardner's beautiful writing about fascinating mathematics, puzzles, and magic tricks has attracted and inspired many people to become mathematicians. At an even deeper level, Martin's writings highlighted exciting research directions and posed open problems which directly influenced mathematical research. Much of my own research was deeply influenced by Martin Gardner, in both recreational mathematics and a branch I call "recreational computer science". While most of this research may have started out recreational, many of the results also have practical applications. I will give a tour of many examples of Gardner's writings and how it inspired new research, from paper folding to mazes to penny puzzles to polyomino packing to magic. I encourage you all to read more Martin Gardner and look for more unsolved research questions and directions.

### Workshop

*3:00 p.m. – 5:00 p.m., Duke Energy Convention Center, Rooms 202 & 203*

Mastery grading is an assessment approach in which students are provided clear learning objectives and grades are directly based on students' ability to demonstrate complete mastery of these objectives by the end of the semester. Recent trends indicate this grading structure encourages a growth-mindset, reduces test anxiety, and improves student gains. This minicourse is designed for new practitioners.
