[K2] N.H. Kuiper, Convex immersions of closed surfaces inThis paper deals specifically with immersions into three-space, and gives a good description of tightness. It gives the decomposition of a tight surface into theE^3,Comm. Math. Helv.35(1961) 85-92.

This paper describes an immersion of the real projective plane with exactly one minimum, one maximum and one saddle point, and it points out how this could be used to produce an eversion of the sphere.
