RESUMO: In this talk, we will consider generic homoclinic classes with periodic points of different indices and assume that there are no-dominations for certain indices. Using Bochi-Bonatti and Franks-Gourmelon perturbation techniques and GIKN criterion, we will show the existence of ergodic measures with more than one vanishing Lyapunov exponents and whose supports are the whole homoclinic class. This is a joint work with Xiaodong Wang.
