报告摘要：

In this talk, we focus on the local theories on the CR and CR singular manifolds. We start with the celebrated paper of Poincare in 1907, in which, among many important results, he proved that hypersurfaces in C^2 are generally not locally equivalent and bidisc is not biholomorphic to the unit ball in C^2. Then we will introduce the celebrated Cartan-Chern-Moser theory and the classical results on Bishop surfaces. We will also talk about some recent developments on the generalized Bishop surfaces.
