Abstract
We find new supergravity solutions generated by D5-branes wrapping a four- cycle and preserving four and two supersymmetries. We first consider the configuration in which the fivebranes wrap a four-cycle in a Calabi-Yau threefold, which preserves four supersymmetries and is a gravity dual to the Coulomb branch of two-dimensional gauge theories with N = (2,2) supersymmetry. We also study the case of fivebranes wrapping a co-associative four-cycle in a manifold of G2-holonomy, which provides a gravity dual of N = (1,1) supersymmetric Yang-Mills theory in two dimensions. We also discuss the addition of unquenched fundamental matter fields to these backgrounds and find the cor- responding gravity solutions with flavor brane sources.
