报告摘要：The original Pick problem is to determine if a finite sequence of points in the unit disk can be mapped to a sequence of complex numbers using a holomorphic function bounded by 1. We discuss a necessary and sufficient condition to solve the Pick problem in a view of reproducing kernel Hilbert spaces, which leads to the complete Nevanlinna-Pick property. In this talk, we start with presenting the general theory of reproducing kernel Hilbert spaces and background of the Pick problem. Then we introduce reproducing kernel Hilbert space with complete Nevanlinna-Pick kernel. It includes Hardy spaces and Dirichlet spaces. We will discuss two questions:
1. Which Hardy space properties can be generalized to spaces with complete Nevanlinna-Pick kernel?
2. Which spaces have complete Nevanlinna-Pick kernel?
