## Abstract

We obtain exact results in α′ for open and closed A-model topological string amplitudes on a large class of toric Calabi-Yau threefolds by using their correspondence with five dimensional gauge theories. The toric Calabi-Yaus that we analyze are obtained as minimal resolution of cones over Y ^{p,q} manifolds and give rise via M-theory compactification to SU(p) gauge theories on ℝ^{4}× S^{1}. As an application we present a detailed study of the local F_{2}case and compute open and closed genus zero Gromov-Witten invariants of the bC_{3}Z_{4} orbifold. We also display the modular structure of the topological wave function and give predictions for higher genus amplitudes. The mirror curve in this case is the spectral curve of the relativistic A _{1} Toda chain. Our results also indicate the existence of a wider class of relativistic integrable systems associated to generic Y ^{p,q} geometries.
