报告摘要： While topological entropy is an invariant for equivalent discrete systems, topological entropy degenerates for continuous systems-flows with fixed point: there exists a pair of equivalent flows so that one has positive entropy and the other has zero entropy. We characterize entropy degeneracy by measure degeneracy which means all ergodic measures with positive entropy loss their invariant property.

This is a joint work with Saghin and Vargas.
