| Research Abstract |
We studied chaotic properties of maps of compact metric spaces by use of topological theory and ergodic theory. In this study, we proved that hereditarily indecomposable continua admit no expansive homeomorphisms. Also by use of Alexandroff-Urysohn metrization theorem we obtained very strong theorems concerning ratios of expanding maps and fractal dimensions. These results are very important in the theories of geometric topology and dynamical systems.
