Abstract：In this talk I am going to talk about the vertex operator realization of the topological vertex from A and B-model respectively. In the B-model side my collaborator and I found out that by dividing the C3 curve into core and asymptotic regions and using Boson-Fermion correspondence, we can construct a generic three-leg correlation function which reformulates the topological vertex in a vertex operator approach. We also propose a conjecture of the correlation function identity which in a degenerate case becomes Zhou’s identity for a Hopf link.
