A bstractWe consider the topological sigma-model on Riemann surfaces with genus g and h holes, and target space $ \mathbb{C}{\mathbb{P}^1} \cong {S^2} $. We calculate the correlation functions of bulk and boundary operators, and study the symmetries of the model and its most general deformation. We study the open/closed topological field theory (TFT) correspondence by summing up the boundaries. We argue that this summation can be understood as a renormalization of the closed TFT. We couple the… Expand

We consider the topological sigma-model on Riemann surfaces with genus g and h holes, and target space CP 1 ∼ S 2 . We calculate the correlation functions of bulk and boundary operators, and study… Expand

We study the topological string on local P2 with O-plane and D-brane at its real locus, using three complementary techniques. In the A-model, we refine localization on the moduli space of maps with… Expand

We consider the topological B-model on local Calabi-Yau geometries. We show how one can solve for the amplitudes by using -algebra symmetries which encode the symmetries of holomorphic… Expand

We study the topological string on compact Calabi-Yau threefolds in the presence of orientifolds and D-branes. In examples, we find that the total topological string amplitude admits a BPS expansion… Expand

Aided by mirror symmetry, we determine the number of holomorphic disks ending on the real Lagrangian in the quintic threefold. We hypothesize that the tension of the domainwall between the two vacua… Expand
