Abstract

We show, for every r>d0r>d\ge 0 or r=d2r=d\ge 2, the existence of a Baire generic set of CdC^d-families of CrC^r-maps (fa)a(1,1)k(f_a)_{a\in (-1,1)^k} of a manifold MM of dimension 2\ge 2, so that for every aa small the map faf_a has infinitely many sinks. When the dimension of the manifold is greater than 33, the generic set is formed by families of diffeomorphisms. This result is a counter-example to a conjecture of Pugh and Shub.
