报告摘要：In differentiable manifold, the relation between the topologic structure and differetiable strucutre is always interesting for geometriers. In this talk, we will introduce the story of low dimensional manifolds, 3 or 4 dimensional gauge theory, and some development about the gauge theory in recent decades. If time is avialable, we will give some open problems to discuss.
