摘要：
I will talk about the definition of topological string theory. Since in the topological string there is a powerful recursion relation among higher genera and lower genera amplitudes which is called the holomorphic anomaly equation, I will briefly discuss its derivation and explain the tadpole cancellation of the new anomalies in open topological string. In the end I will point out some open questions and some connection with mathematical study on the geometric invariants. |
