A matrix model for the topological string: Deriving the BKMP conjecture

Regular Seminar Amir-Kian Kashani-Poor (ENS, Paris)

room E303 Queens Building
abstract:

In this talk, I will discuss work in progress with Bertrand Eynard, in which we derive the BKMP remodelling the B-model conjecture, in the large radius limit. This is the claim that Gromov-Witten invariants of any toric Calabi-Yau 3-fold coincide with the spectral invariants of the mirror curve. Our method consists in explicitly constructing a matrix model which reproduces the topological string partition function obtained via the vertex formalism, and then demonstrating that the spectral curve of this matrix model coincides with the mirror geometry.

The wave function behavior of the open topological string

Regular Seminar Amir-Kian Kashani-Poor (University of Amsterdam)

room Huxley 503
abstract:

Suppose we could calculate the string partition function to all genera using worldsheet methods. What could we learn from this expression about a potentially underlying (non-perturbative) target space description of the theory? We address this question in the context of the open topological A-model.
