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

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

 at: 14:00 QMWroom 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)

 at: 13:30 ICroom 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.
