报告内容: We will begin the talk by the Riemann surface of a meromorphic function. We will introduce the singularities of the inverse of a meromorphic function over a value which are the boundary points of the Riemann surface. After that, we introduce the Wiman-Valiron theory on a direct tract which was developed recently and its applications on ODEs on the complex plane. The size of disk on which the theory holds will be discussed.
