Brane Tilings for Orientifolds
Brane tilings, often also refered to as dimers, are currently the most powerful tool available to study the 4D low-energy effective gauge theories arising from D3-branes at toric Calabi-Yau 3-fold singularities. From a mathematical viewpoint, brane tilings are just bipartite graphs, there bipartite means that one can color the vertices of a graph with two colors (usually black and white) such t...
متن کاملAnomaly Cancellations in Brane Tilings
We re-interpret the anomaly cancellation conditions for the gauge symmetries and the baryonic flavor symmetries in quiver gauge theories realized by the brane tilings from the viewpoint of flux conservation on branes. ∗ E-mail: [email protected]
متن کاملBrane Tilings and Their Applications
We review recent developments in the theory of brane tilings and four-dimensional N = 1 supersymmetric quiver gauge theories. This review consists of two parts. In part I, we describe foundations of brane tilings, emphasizing the physical interpretation of brane tilings as fivebrane systems. In part II, we discuss application of brane tilings to AdS/CFT correspondence and homological mirror sym...
متن کاملScheme dependence and the NSVZ β - function
We investigate the connection between the NSVZ and the DRED forms of the gauge β-function in an N = 1 supersymmetric gauge theory. We construct a coupling constant redefinition that relates the two forms up to four loops. By abelian calculations, we are able to infer the complete non-abelian form of β
متن کاملGale-Robinson Sequences and Brane Tilings
This article is concerned with a variant of the Gale-Robinson integer sequence [Gal91], i.e. {xn} satisfying xnxn−N = xn−rxn−N+r + xn−sxn−N+s, where we include a second alphabet of variables, {y1, y2, . . . , yn}, that breaks the symmetry of this recurrence. This deformation is motivated by the theory of cluster algebras with principal coefficients. The undeformed version of this sequence has b...
