Title: Variety of minimal rational tangents and its applications
Abstract: The theory of variety of minimal rational tangents (VMRT), introduced by Hwang and Mok, has been used to solve lots of problems in algebraic geometry, e.g., the Kähler deformation rigidity of irreducible Hermitian symmetric spaces and the Lazarsfeld problem. In this short course, I will review some basic notions, examples and techniques in VMRT theory. Also, I will talk about a recent development of the so-called sub-VMRT theory, which was introduced by Mok and Zhang, and its applications in the rigidity problems of Schubert cycles. Moreover, I will discuss its application in several complex variables.
