Title:  Oscillatory integrals on T-dual branes

Abstract:   I will describe how to compute oscillatory integrals on T-dual branes in the LG model mirror to a toric variety. The result is a genus-0 descendant Gromov-Witten potential. By identifying this T-dual brane with a Lefschetz thimble one can obtain the asymptotic expansion of this potential, and relates to the Gamma II conjecture which concerns the asymptotic expansion of solutions to the quantum differential equations.
