Title:  Search the quantum symmetry in topology

Abstract:  There are many examples where the mathematics from the same root seems to be far apart from each other. I will illustrate such a phenomenon using three examples: flop, McKay correspondence and singularities/Calabi-Yau correspondence. On the other hand, there is a general principal from physics that the quantum world should be more uniform than classical world. It surjects that they may be connected after a quantization process. In the talk, I will demonstrate such a "quantum symmetry" for quantum cohomology.
