Topological strings and their physical applications
We give an introductory review of topological strings and their application to various aspects of superstrings and supersymmetric gauge theories. This review includes developing the necessary mathematical background for topological strings, such as the notions of Calabi-Yau manifold and toric geometry, as well as physical methods developed for solving them, such as mirror symmetry, large N dual...
متن کاملTopological Strings
Following some recent works of Witten, we explore topological non-linear sigma models (TSM). W e construct 2-D topological gravity which is then coupled to the TSM resulting in a topological bosonic string theory. This theory has a nontachyonic vacuum and can be formulated on any even dimensional target manifold which admits some non-trivial topology. It is then shown that the metric independen...
متن کاملHypermultiplets and Topological Strings
The c-map relates classical hypermultiplet moduli spaces in compactifications of type II strings on a Calabi-Yau threefold to vector multiplet moduli spaces via a further compactification on a circle. We give an off-shell description of the c-map in N = 2 superspace. The superspace Lagrangian for the hypermultiplets is a single function directly related to the prepotential of special geometry, ...
متن کاملKnot Invariants and Topological Strings
We find further evidence for the conjecture relating large N Chern-Simons theory on S with topological string on the resolved conifold geometry by showing that the Wilson loop observable of a simple knot on S (for any representation) agrees to all orders in N with the corresponding quantity on the topological string side. For a general knot, we find a reformulation of the knot invariant in term...
متن کاملS-duality and topological strings
In this paper we show how S-duality of type-IIB superstrings leads to an Sduality relating Aand B-model topological strings on the same Calabi-Yau as had been conjectured recently: D-instantons of the B-model correspond to A-model perturbative amplitudes and D-instantons of the A-model capture perturbative B-model amplitudes. Moreover this confirms the existence of new branes in the two models....
