Remarks on quiver gauge theories from open topological string theory | | Nils Carqueville

23 Dec 2009 | | Abstract: | We study effective quiver gauge theories arising from a stack of D3-branes on
certain Calabi-Yau singularities. Our point of view is a first principle
approach via open topological string theory. This means that we construct the
natural A-infinity-structure of open string amplitudes in the associated
D-brane category. Then we show that it precisely reproduces the results of the
method of brane tilings, without having to resort to any effective field theory
computations. In particular, we prove a general and simple formula for
effective superpotentials. | | Source: | arXiv, 0912.4699 | | Services: | Forum | Review | PDF | Favorites | |
