Query: On the abundance of SRB measures   We prove the abundance of Sinai-Ruelle-Bowen measures for diffeomorphisms
away from ones with a homoclinic tangency. This is motivated by conjectures of
Palis on the existence of physical (Sinai-Ruelle-Bowen) measures for global
dynamics. The main novelty in this paper is that we have to deeply study Gibbs
$cu$-states in different levels. Note that we have to use random perturbations
to give some upper bound of the level of Gibbs $cu$-states.
