In this work, we study families of singular surfaces in C 3 parametrized by A-finitely determined map germs. We consider the topological triviality and Whitney equisingularity of an unfolding F of a finitely determined map germ f : (C 2 , 0) → (C 3 , 0). We investigate the following conjecture: topological triviality implies Whitney equisingularity of the unfolding F ? We provide a complete answer to this conjecture, given counterexamples showing how the conjecture can be false. * M.A.S. Ruas: ICMC, Universidade de São Paulo, Av. do Trabalhador São
