| Research Abstract |
We studied about the computability of metric spaces from the topological point of view. We also studied on set-theoretic topology and dimension theory of topological spaces. In particular, we studied the relations between the order and topological structures on the domains of the formal balls of metric spaces. Concerning dimension theory, we investigated the inductive dimension modulo absolute multiplicative class M(α) and additive class A(α), and constructed the examples which show the differences of the values of these dimensions. We also improved the additive theorem and the product theorem for the inductive dimensions. We also considered the spaces which are finite union of locally compact subspaces and gave a characterization of strong paracompactness by means of the selection of multi-valued mappings
