Codimension-Two Defects and SYM on Orbifolds
Roman Mauch, Lorenzo Ruggeri
We study SYM theories on spaces with orbifold singularities via an equivalent description in terms of gauge theories on smooth manifolds with insertions of Gukov-Witten and…
From 5d Flat Connections to 4d Fluxes (the Art of Slicing the Cone)
Jim Lundin, Roman Mauch, Lorenzo Ruggeri
We compute the Coulomb branch partition function of the 4d vector multiplet on closed simply-connected quasi-toric manifolds . This includes a large class of the…
Super Yang-Mills on Branched Covers and Weighted Projective Spaces
Roman Mauch, Lorenzo Ruggeri
In this work we conjecture the Coulomb branch partition function, including flux and instanton contributions, for the vector multiplet on weighted projective space…
The Equivariant B model
Guido Festuccia, Roman Mauch, Maxim Zabzine
In this work, we introduce an equivariant deformation of the model on the sphere with a -action. We present the deformed supersymmetry transformations and corresponding L…
