概要
【講演要旨】We give conditions for the existence of singular maps with only fold and cusp singularities. We obtain that the existence of such singular maps in even dimensions puts restrictions on the signature of the domain and on the dimension of the target manifold. Cobordism invariants are introduced of such cusp maps and we study the cobordism class of the source manifold.
