Strings from Feynman Graph counting : without large N
Robert de Mello Koch, Sanjaye Ramgoolam
A well-known connection between n strings winding around a circle and permutations of n objects plays a fundamental role in the string theory of large N two dimensional Yang Mills…
Invariants of Toric Seiberg Duality
Amihay Hanany, Yang-Hui He, Vishnu Jejjala +3
Three-branes at a given toric Calabi-Yau singularity lead to different phases of the conformal field theory related by toric (Seiberg) duality. Using the dimer model/brane tiling d…
Calabi-Yau Orbifolds and Torus Coverings
Amihay Hanany, Vishnu Jejjala, Sanjaye Ramgoolam +1
The theory of coverings of the two-dimensional torus is a standard part of algebraic topology and has applications in several topics in string theory, for example, in topological s…
The Beta Ansatz: A Tale of Two Complex Structures
Amihay Hanany, Yang-Hui He, Vishnu Jejjala +3
Brane tilings, sometimes called dimer models, are a class of bipartite graphs on a torus which encode the gauge theory data of four-dimensional SCFTs dual to D3-branes probing tori…
