Remodeling the B-model

Understand

We propose a complete, new formalism to compute unambiguously B-model open and closed amplitudes in local Calabi-Yau geometries, including the mirrors of toric manifolds.

• The formalism is based on the recursive solution of matrix models recently proposed by Eynard and Orantin.
• The resulting amplitudes are non-perturbative in both the closed and the open moduli.
• The formalism can then be used to study stringy phase transitions in the open/closed moduli space.
