Gravitational algebras and applications to nonequilibrium physics
Michele Cirafici
This note aims to offer a non-technical and self-contained introduction to gravitational algebras and their applications in the nonequilibrium physics of gravitational systems. We…
On the Nonequilibrium Dynamics of Gravitational Algebras
Michele Cirafici
We explore nonequilibrium features of certain operator algebras which appear in quantum gravity. The algebra of observables in a black hole background is a Type $\mathrm{II}_\infty…
Positivity for Higgs vector bundles: criteria and applications
Ugo Bruzzo, Armando Capasso, Beatriz Graña Otero
Working in the category of smooth projective varieties over an algebraically closed field of characteristic 0, we review notions of ampleness and numerical nefness for Higgs bundle…
Hopf algebroids and twists for quantum projective spaces
Ludwik Dabrowski, Giovanni Landi, Jacopo Zanchettin
We study the relationship between antipodes on a Hopf algebroid in the sense of Böhm-Szlachanyi and the group of twists that lies inside the associated convolution al…
Seiberg-Witten differentials on the Hitchin base
Ugo Bruzzo, Peter Dalakov
In this note we describe explicitly, in terms of Lie theory and cameral data, the covariant (Gauss--Manin) derivative of the Seiberg--Witten differential defined on the weight-one…
D3-brane supergravity solutions from Ricci-flat metrics on canonical bundles of Kähler-Einstein surfaces
Ugo Bruzzo, Pietro Fré, Umar Shahzad +1
D3-brane solutions of type IIB supergravity can be obtained by means a classical ansatz involving a harmonic warp factor and two summands, the first being the flat Minkowskian metr…
Solutions and Singularities of the Semigeostrophic Equations via the Geometry of Lagrangian Submanifolds
Roberto D'Onofrio, Giovanni Ortenzi, Ian Roulstone +1
Using Monge-Ampère geometry, we study the singular structure of a class of nonlinear Monge-Ampère equations in three dimensions, arising in geophysical fluid dynamics. We extend se…
Toda equations for surface defects in SYM and instanton counting for classical Lie groups
Giulio Bonelli, Fran Globlek, Alessandro Tanzini
The partition function of super Yang-Mills theories with arbitrary simple gauge group coupled to a self-dual -background is shown to be fully determined by study…
Levi-Civita connections on quantum spheres
Joakim Arnlind, Kwalombota Ilwale, Giovanni Landi
We introduce -deformed connections on the quantum 2-sphere and 3-sphere, satisfying a twisted Leibniz rule in analogy with -deformed derivations. We show that such connection…
M2-branes and -Painlevé equations
Giulio Bonelli, Fran Globlek, Naotaka Kubo +2
In this paper we investigate a novel connection between the effective theory of M2-branes on and the $\ma…
Irregular Liouville correlators and connection formulae for Heun functions
Giulio Bonelli, Cristoforo Iossa, Daniel Panea Lichtig +1
We perform a detailed study of a class of irregular correlators in Liouville Conformal Field Theory, of the related Virasoro conformal blocks with irregular singularities and of th…
Lie Bi-Algebras on the Non-Commutative Torus
Giovanni Landi, S. G. Rajeev
Infinitesimal symmetries of a classical mechanical system are usually described by a Lie algebra acting on the phase space, preserving the Poisson brackets. We propose that a quant…
Resolution a la Kronheimer of singularities and the Monge-Ampere equation for Ricci-flat Kaehler metrics in view of D3-brane solutions of supergravity
Massimo Bianchi, Ugo Bruzzo, Pietro Fré +1
We analyze the relevance of the generalized Kronheimer construction for the gauge-gravity correspondence. We study the general structure of IIB supergravity D3-brane solutions on c…
Exact solution of Kerr black hole perturbations via CFT and instanton counting. Greybody factor, Quasinormal modes and Love numbers
Giulio Bonelli, Cristoforo Iossa, Daniel Panea Lichtig +1
We give explicit expressions for the finite frequency greybody factor, quasinormal modes and Love numbers of Kerr black holes by computing the exact connection coefficients of the…
Gauge groups and bialgebroids
Xiao Han, Giovanni Landi
We study the Ehresmann--Schauenburg bialgebroid of a noncommutative principal bundle as a quantization of the gauge groupoid of a classical principal bundle. We show that the gauge…
Instantons to the people: the power of one-form symmetries
Giulio Bonelli, Fran Globlek, Alessandro Tanzini
We show that the non-perturbative dynamics of super Yang-Mills theories in a self-dual -background and with an arbitrary simple gauge group is fully determined b…
On the Kadomtsev-Petviashvili hierarchy in an extended class of formal pseudo-differential operators
Jean-Pierre Magnot, Vladimir Rubtsov
We study the existence and uniqueness of the Kadomtsev-Petviashvili (KP) hierarchy solutions in the algebra of $\F Cl(S^1,\K^n)$ of formal classical pseudo-differential operators.…
Koszul complexes and spectral sequences associated with Lie algebroids
U. Bruzzo, V. N. Rubtsov
We study some spectral sequences associated with a locally free -module which has a Lie algebroid structure. Here is either a complex manifold or a r…
ADHM in 8d, coloured solid partitions and Donaldson-Thomas invariants on orbifolds
Giulio Bonelli, Nadir Fasola, Alessandro Tanzini +1
We study the moduli space of invariant BPS conditions in supersymmetric gauge theory on non-commutative by means of an ADHM-like quiver construction and we…
A note on discrete dynamical systems in theories of class
Michele Cirafici
In this note we consider the set of line operators in theories of class . We show that this set carries the action of a natural discrete dynamical system associated with the BPS…

Fabrizio Del Monte, Harini Desiraju, Pavlo Gavrylenko
We prove that the isomonodromic tau function on a torus with Fuchsian singularities and generic monodromies in can be written in terms of a Fredholm determinant…
