Flags of sheaves, quivers and symmetric polynomials

Giulio Bonelli, Nadir Fasola, Alessandro Tanzini

We study the representation theory of the nested instantons quiver presented in [1], which describes a particular class of surface defects in four-dimensional supersymmetric gauge…

Deformed Hermitian Yang-Mills connections, extended gauge group and scalar curvature

Enrico Schlitzer, Jacopo Stoppa

The deformed Hermitian Yang-Mills (dHYM) equation is a special Lagrangian type condition in complex geometry. It requires the complex analogue of the Lagrangian phase, defined for…

On the Koszul formula in noncommutative geometry

Jyotishman Bhowmick, Debashish Goswami, Giovanni Landi

We prove a Koszul formula for the Levi-Civita connection for any pseudo-Riemannian bilinear metric on a class of centered bimodule of noncommutative one-forms. As an application to…

Circular quiver gauge theories, isomonodromic deformations and fermions on the torus

Giulio Bonelli, Fabrizio Del Monte, Pavlo Gavrylenko +1

We study the relation between class S theories on punctured tori and isomonodromic deformations of flat SL(N) connections on the two dimensional torus with punctures. Turning on th…

Quantum Line Defects and Refined BPS Spectra

Michele Cirafici

In this note we study refined BPS invariants associated with certain quantum line defects in quantum field theories of class . Such defects can be specified via geomet…

Crepant Resolutions of and the Generalized Kronheimer Construction (in view of the Gauge/Gravity Correspondence)

Ugo Bruzzo, Annamaria Fino, Pietro Fré +2

As a continuation of a general program started in two previous publications, in the present paper we study the Kähler quotient resolution of the orbifold $\mathbb{C}^3/\mathbb{Z}_4…

gauge theory, free fermions on the torus and Painlevé VI

Giulio Bonelli, Fabrizio Del Monte, Pavlo Gavrylenko +1

In this paper we study the extension of Painlevé/gauge theory correspondence to circular quivers by focusing on the special case of theory. We show that t…
