Stepwise Projection: Toward Brane Setups for Generic Orbifold Singularities
Bo Feng, Amihay Hanany, Yang-Hui He +1
The construction of brane setups for the exceptional series E6,E7,E8 of SU(2) orbifolds remains an ever-haunting conundrum. Motivated by techniques in some works by Muto on non-Abe…
Discrete Torsion, Covering Groups and Quiver Diagrams
Bo Feng, Amihay Hanany, Yang-Hui He +1
Without recourse to the sophisticated machinery of twisted group algebras, projective character tables and explicit values of 2-cocycles, we here present a simple algorithm to stud…
Discrete Torsion, Non-Abelian Orbifolds and the Schur Multiplier
Bo Feng, Amihay Hanany, Yang-Hui He +1
Armed with the explicit computation of Schur Multipliers, we offer a classification of SU(n) orbifolds for n = 2,3,4 which permit the turning on of discrete torsion. This is in res…
An Observation on Finite Groups and WZW Modular Invariants
Bo Feng, Yang-Hui He
In this short note, inspired by much recent activity centered around attempts to formulate various correspondences between the classification of affine SU(k) WZW modular-invariant…
D-Brane Gauge Theories from Toric Singularities and Toric Duality
Bo Feng, Amihay Hanany, Yang-Hui He
Via partial resolution of Abelian orbifolds we present an algorithm for extracting a consistent set of gauge theory data for an arbitrary toric variety whose singularity a D-brane…
