<p><strong>Summary:</strong> The adjective tropical was chosen by French mathematicians to honor Imre Simon, the Brazilian originator of min-plus algebra, which grew into this field. The basic object of study is the tropical semiring consisting of the real numbers R with a point at infinity under the operations of equals minimum and equals plus.</p></div></div></div>Counting Irreducible Polynomials over Finite Fields Using the Inclusion-Exclusion Principle
