Description
Observables of the A-model open topological string encode counts of holomorphic curves with Lagrangian boundary conditions. When Lagrangian A-branes have non-compact support, the count of open holomorphic curves depends on the asymptotic geometry of Lagrangians at infinity. In this talk I will show how the asymptotic geometry of three Legendrian tori in contact S^5 encodes a set of equations whose solutions include the topological vertex, and its analytic continuation to other large volume regions in the moduli space of three toric branes in C^3. Based on joint works with Ekholm-Nakamura, and Ekholm-Shende.
