Abstract: | Starting from proofing compressing mapping image of function (K<1) definiting on Bounded closed set is compressing closely Mapping Image. The thesis mainly discuss Topological Number proverty of compressing closely Mapping Image Field about Function (K<1) definiting on closure of bounded openset. |

Keywords: | compressing closely mapping image invariant homotopy class open mapping homotopy mapping |
