Quiver $W_{ε_{1}, ε_{2}}$ algebras of 4d $N = 2$ gauge theories

Fabrizio Nieri, Yegor Zenkevich

We construct an $ε$ -deformation of W algebras, corresponding to the additive version of quiver $W_{q, t^{- 1}}$ algebras which feature prominently in the 5d version of the BPS…

Localization of 4d $N = 1$ theories on $D^{2} \times T^{2}$

Pietro Longhi, Fabrizio Nieri, Antonio Pittelli

We consider 4d $N = 1$ gauge theories with R-symmetry on a hemisphere times a torus. We apply localization techniques to evaluate the exact partition function through a coh…

3d Mirror Symmetry from S-duality

Fabrizio Nieri, Yiwen Pan, Maxim Zabzine

We consider type IIB $S L (2, Z)$ symmetry to relate the partition functions of different 5d supersymmetric Abelian linear quiver Yang-Mills theories in the $Ω$ -background an…

Bootstrapping the $S^{5}$ partition function

Fabrizio Nieri, Yiwen Pan, Maxim Zabzine

We consider $U (N)$ SQCD on $S^{5}$ and propose a Higgs branch-like expression for its partition function. We support the result by arguing that the knowledge of certain BPS codimensi…

$q$ -Virasoro modular triple

Fabrizio Nieri, Yiwen Pan, Maxim Zabzine

Inspired by 5d supersymmetric Yang-Mills theories placed on the compact space $S^{5}$ , we propose an intriguing algebraic construction for the $q$ -Virasoro algebra. We show…
