| Research Abstract |
We considered the dynamical behavior of maps on graphs, compacta with good local property. Main results are the following : (1) We established a Barge-Martin type theorem for graph self-maps for which the set of periodic points is dense. (2) For a self-map of a compactum we gave a necessary and sufficient condition for the chain recurrent set to be precisely the set of periodic points. (3) Given an n-dimensional locally (n-1)-connected compact space X (n>=1) and a finite Borel measure μwithout atoms at isolated points, we proved that for a generic map f : X -> X, the set of points which are chain recurrent under f has μ-measure zero.
