Airy structures and deformations of curves in surfaces
Journal of the London Mathematical Society, Volume 109, Issue 1, January 2024.Abstract An embedded curve in a symplectic surface Σ⊂X$\Sigma \subset X$ defines a smooth deformation space B$\mathcal {B}$ of nearby embedded curves. A key idea of Kontsevich and Soibelman is to equip the symplectic surface X$X$ with a foliation in order to study the deformation space B$\mathcal {B}$.

On constraints of the (β-deformed) partition functions with W-representations
Physics Letters BWe investigate the constraints of the (β-deformed) partition functions with W-representations in the literature, which can be realized by the interpolating two-matrix models (two β-ensembles).

Black hole entropy and soft hair
Journal of High Energy Physics, 2018 A set of infinitesimal Virasoro L ⊗ Virasoro R diffeomorphisms are presented which act non-trivially on the horizon of a generic Kerr black hole with spin J.

Infinite $\mathrm{T\bar T}$-like symmetries of compactified LST
SciPost PhysicsWe show that the three-dimensional asymptotically linear dilaton background that arises in the near-horizon decoupling region of NS5-branes compactified on $T^4$ admits boundary conditions that lead to an infinite set of symmetries.

From CFT to Ramond super-quantum curves
Journal of High Energy Physics, 2018 As we have shown in the previous work, using the formalism of matrix and eigenvalue models, to a given classical algebraic curve one can associate an infinite family of quantum curves, which are in one-to-one correspondence with singular vectors of a ...

Whittaker Categories for the Virasoro Algebra [PDF]
Communications in Algebra, 2013 This paper builds on earlier work, where the authors described Whittaker modules for the Virasoro algebra. Using a framework of Batra and Mazorchuk, the current paper investigates a category of Virasoro algebra modules that includes Whittaker modules. Results in this paper include a classification of the simple modules in the category and a description

Strings, Virasoro sandwiches and worldsheet horizons
Physics Letters BWe revisit the canonical quantization of free bosonic closed string theory and observe that the physicality of states requires vanishing of the worldsheet Virasoro algebra generators sandwiched between any two physical states.

Conserved charges and asymptotic symmetries of BTZ-like black holes in Einstein-bumblebee gravity
European Physical Journal C: Particles and FieldsUsing the solution phase space method, we investigate the conserved charges of BTZ-like black holes in Einstein-bumblebee gravity. Our study shows that the black hole mass, angular momentum and entropy are influenced by the Lorentz-violating parameter ...

Modules for loop Affine-Virasoro algebras
Journal of Algebra and Its Applications, 2020 In this paper, we study the representations of loop Affine-Virasoro algebras. As they have canonical triangular decomposition, we define Verma modules and their irreducible quotients. We give necessary and sufficient condition for a irreducible highest weight module to have finite dimensional weight spaces.
