Localization, Factorization and Dualities for Elliptic Kernels
Alessio Fontanarossa, Fabrizio Nieri, Antonio Pittelli
We study the exact partition function of 4d supersymmetric gauge theories on a torus times a cylinder , where is a finite interval carr…
Trace Formulas for Deformed W-Algebras
Fabrizio Nieri
We investigate trace formulas in -deformed W-algebras, highlighting a novel connection to the modular double of -deformed W-algebras. In particular, we s…
Defects at the Intersection: the Supergroup Side
Fabrizio Nieri
We consider two seemingly different theories in the -background: one arises upon the most generic Higgsing of a 5d gauge theory coupled to matter,…
Intersecting Defects and Supergroup Gauge Theory
Taro Kimura, Fabrizio Nieri
We consider 5d supersymmetric gauge theories with unitary groups in the -background and study codim-2/4 BPS defects supported on orthogonal planes intersecting at the origin alo…
Quiver algebras of 4d gauge theories
Fabrizio Nieri, Yegor Zenkevich
We construct an -deformation of W algebras, corresponding to the additive version of quiver algebras which feature prominently in the 5d version of the BPS…
Localization of 4d theories on
Pietro Longhi, Fabrizio Nieri, Antonio Pittelli
We consider 4d gauge theories with R-symmetry on a hemisphere times a torus. We apply localization techniques to evaluate the exact partition function through a coh…
