Some dynamical properties of continuous semi-flows having topological transitivity. (English) Zbl 1098.37503
Summary: We investigate the dynamical properties of continuous semi-flows having topological transitivity on a compact metric space.The main results are as follows: (1) a continuous semi-flow with topological transitivity and positive Lyapunov stability is an almost periodic minimal flow; (2) a continuous semi-flow is uniformly almost periodic minimal flow if and only if it is topologically ergodic and has positively Lyapunov stable points; (3) a continuous flow with topological transitivity on a closed surface is either chaos in the sense of Takens and Ruelle or uniformly almost periodic minimal flow on Torus.
