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…

$t t^{*}$ Toda equations for surface defects in $N = 2$ SYM and instanton counting for classical Lie groups

Giulio Bonelli, Fran Globlek, Alessandro Tanzini

The partition function of $N = 2$ super Yang-Mills theories with arbitrary simple gauge group coupled to a self-dual $Ω$ -background is shown to be fully determined by study…

Levi-Civita connections on quantum spheres

Joakim Arnlind, Kwalombota Ilwale, Giovanni Landi

We introduce $q$ -deformed connections on the quantum 2-sphere and 3-sphere, satisfying a twisted Leibniz rule in analogy with $q$ -deformed derivations. We show that such connection…

M2-branes and $q$ -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 $(C^{2} / Z_{2} \times C^{2} / Z_{2}) / Z_{k}$ 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…
