Title：New recursion relations of the local Gromov-Witten invariants.

Speaker: Prof. Zhou Jian, Math. Dept of Tsinghua University

Time: 9:30-12:00 am, Friday, Dec. 25th

Lecture room: Room 1328, Resource building

Abstract: 
In this 2 and a half hour talk, I will firstly describe the known local Gromov-Witten invariants and then explain the new recursion relations I obtained recently from which the Riemann surface information will naturally appears. (Comment by Fan,Huijun: Zhou's work should be an important progress of the research in the local GW invariants (theory, hoped to be appearred), which has close relation to the LG model, and sigma-model. )
