Eliashberg's $h$-principle and generic maps of surfaces with prescribed singular locus

Geometric Topology 2023-11-30 v3

Abstract

We extend Y.Eliashberg's hh-principle to smooth maps of surfaces which are allowed to have cusp singularities, as well as folds. More precisely, we prove a necessary and sufficient condition for a given map of surfaces to be homotopic to one with given loci of folds and cusps. Then we use these results to obtain a necessary and sufficient condition for a subset of a surface MM to be realizable as the critical set of some generic smooth map from MM to a given surface NN.
