On the number of topologically non-equivalent functions with one degenerate saddle critical point on two-dimensional sphere, II
Abstract
In this paper we consider the smooth functions with three critical values on two-dimensional sphere $S^2$, that possess only one (degenerate) saddle critical point in addition to $M$ local maxima and $m$ local minima. For any natural $M$ and $m$ we calculate the number of topologically non-equivalent such functions.
