The exact superconformal R-symmetry maximizes a

K Intriligator, B Wecht - Nuclear Physics B, 2003 - Elsevier
An exact and general solution is presented for a previously open problem. We show that the
superconformal R-symmetry of any 4d SCFT is exactly and uniquely determined by a …

Brane dimers and quiver gauge theories

S Franco, A Hanany, D Vegh, B Wecht… - Journal of High …, 2006 - iopscience.iop.org
We describe a technique which enables one to quickly compute an infinite number of toric
geometries and their dual quiver gauge theories. The central object in this construction is …

Counting BPS operators in gauge theories: quivers, syzygies and plethystics

S Benvenuti, B Feng, A Hanany… - Journal of High Energy …, 2007 - iopscience.iop.org
We develop a systematic and efficient method of counting single-trace and multi-trace BPS
operators with two supercharges, for world-volume gauge theories of N D-brane probes for …

Gauge theories from toric geometry and brane tilings

S Franco, A Hanany, D Martelli, J Sparks… - Journal of High …, 2006 - iopscience.iop.org
We provide a general set of rules for extracting the data defining a quiver gauge theory from
a given toric Calabi-Yau singularity. Our method combines information from the geometry …

The Geometric Dual of a–Maximisation for Toric Sasaki–Einstein Manifolds

D Martelli, J Sparks, ST Yau - Communications in mathematical physics, 2006 - Springer
We show that the Reeb vector, and hence in particular the volume, of a Sasaki–Einstein
metric on the base of a toric Calabi–Yau cone of complex dimension n may be computed by …

Dimer models and toric diagrams

A Hanany, KD Kennaway - arxiv preprint hep-th/0503149, 2005 - arxiv.org
We propose a duality between quiver gauge theories and the combinatorics of dimer
models. The connection is via toric diagrams together with multiplicities associated to points …

Toric geometry, Sasaki–Einstein manifolds and a new infinite class of AdS/CFT duals

D Martelli, J Sparks - Communications in mathematical physics, 2006 - Springer
Recently an infinite family of explicit Sasaki–Einstein metrics Y p, q on S 2× S 3 has been
discovered, where p and q are two coprime positive integers, with q< p. These give rise to a …

Dimer models from mirror symmetry and quivering amoebae

B Feng, YH He, KD Kennaway, C Vafa - 2008 - projecteuclid.org
Dimer models are 2-dimensional combinatorial systems that have been shown to encode
the gauge groups, matter content and tree-level superpotential of the world-volume quiver …

An infinite family of superconformal quiver gauge theories withSasaki-Einstein duals

S Benvenuti, S Franco, A Hanany… - Journal of High …, 2005 - iopscience.iop.org
We describe an infinite family of quiver gauge theories that are AdS/CFT dual to a
corresponding class of explicit horizon Sasaki-Einstein manifolds. The quivers may be …

Quivers, tilings, branes and rhombi

A Hanany, D Vegh - Journal of High Energy Physics, 2007 - iopscience.iop.org
We describe a simple algorithm that computes the recently discovered brane tilings for a
given generic toric singular Calabi-Yau threefold. This therefore gives AdS/CFT dual quiver …
