Description
Abstract: Dualities in 4, 3 and 2 dimensions are related by different types of dimensional reduction limits. These can be effectively exploited to find new dualities from already known ones. As a concrete example, I will review the reduction of 4d N=1 dualities to 2d N=(0,2) ones by compactification on a two-sphere with a topological twist. In particular, I will present a new duality for a USp(2N) gauge theory with antisymmetric matter and show how this can be derived by iteration of a more fundamental duality, in analogy with similar derivations for parent dualities in four and three dimensions.
