2 Toric Duality , Seiberg Duality and Picard - Lefschetz Transformations
Toric Duality arises as an ambiguity in computing the quiver gauge theory living on a D3-brane which probes a toric singularity. It is reviewed how, in simple cases Toric Duality is Seiberg Duality. The set of all Seiberg Dualities on a single node in the quiver forms a group which is contained in a larger group given by a set of Picard-Lefschetz transformations. This leads to elements in the g...

متن کاملSQCD and Seiberg duality
We revisit the study of singular points in the Coulomb branch of N = 2 SQCD in four dimensions with gauge group SU(N). For certain choices of the mass parameters these vacua are not lifted by a mass term for the chiral multiplet in the adjoint representation. By using recent results about the M5 brane description of N = 1 theories we study the resulting vacua and argue that the low-energy effec...
متن کاملSeiberg Duality is an Exceptional Mutation
The low energy gauge theory living on D-branes probing a del Pezzo singularity of a noncompact Calabi-Yau manifold is not unique. In fact there is a large equivalence class of such gauge theories related by Seiberg duality. As a step toward characterizing this class, we show that Seiberg duality can be defined consistently as an admissible mutation of a strongly exceptional collection of cohere...
متن کاملSymmetries of Toric Duality
This paper serves to elucidate the nature of toric duality dubbed in hep-th/0003085 in the construction for world volume theories of D-branes probing arbitrary toric singularities. This duality will be seen to be due to certain permutation symmetries of multiplicities in the gauged linear sigma model fields. To this symmetry we shall refer as “multiplicity symmetry.” We present beautiful combin...
