Outline of Final Research Achievements

I studied representation spaces induced by smooth actions on manifolds of finite groups. In particular, I studied finite group smooth actions on spheres. The Smith problem, whether tangential representation spaces over fixed points of a sphere with just two fixed points are isomorphic?, is fundamental one for transformation group theory. I determinied the Smith set which consists of the differences of tangential representative spaces over such a sphere for some class of finite groups. I also gave a sufficient and necessary condition for a finite group to be a gap group by viewing centralizers and normalizers.
