报告摘要：

   Modern enumerative algebraic geometry is a broad and important branch in Geometry which has close relation and impact on theoretical physics such as string theory, Yang-Mills gauge theory and quantum field theory.  The basic invariants in enumerative geometry are Gromov-Witten invariants, Donaldson-Thomas, Gopakumar-Vafa invariants and Vafa-Witten invariants etc. In this talk， I will review the basic history of Algebraic Geometry, and the main  research areas. Then I will mainly focus on enumerative algebraic geometry and introduce the counting invariants. The last part of the talk is focusing on the S-duality conjecture of Vafa-Witten which is motivated by the  electric and magnetic field  duality in N=4 supersymmetric Yang-Mills gauge theory.
