摘要：We study the dynamical systems satisfying some weak specification-like properties. We show that there is a dichotomy for the space of invariant measures：it is a singleton (the system is unique ergodic) if and only if the system has zero topological entropy, otherwise it is a Poulsen simplex. If in addition the system is asymptotically entropy expansive, then ergodic measures of intermediate entropies are generic in certain compact subspaces.
