Title: Oscillatory integrals on Tdual branes
Abstract: I will describe how to compute oscillatory integrals on Tdual branes in the LG model mirror to a toric variety. The result is a genus0 descendant GromovWitten potential. By identifying this Tdual 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.
