Probablistic construction of CFT and applications to Virasoro conformal blocks.
We present a probabilistic construction of Liouville Conformal Field Theory (LCFT), starting with Segal’s axioms and the structure constants (the DOZZ formula). Then, we show how to extract the Virasoro algebra from the semigroup of annuli, and use this data in the spectral theory of the Hamiltonian. Finally, we...

Quantization of cluster Poisson varieties and its applications to CFT
The first talk will be an introductory lecture about cluster quantization. In the second talk we plan to cover some more advanced subjects (integration on moduli and recurrence relations using clusters). The third talk concerns Steinberg symbols, vertex operators and clusters.

On quantum curves and q-deformed isomonodromic equations.
In recent years, a rich interplay has developed between topological string theory, quantum operators associated with mirror curves, and isomonodromic equations together with their q-deformations. In this talk, I will focus on two operators: the well-known modified Mathieu operator and the less familiar but equally intriguing...

Tensor categories arising from the Virasoro algebra and quantum groups.
When studying conformal field theory in two dimensions, one naturally encounters primary fields and their operator product expansions. These can be interpreted as simple objects and tensor products in a tensor category.
Two well-known sources of tensor categories are quantum groups and vertex operator algebras...

Wess-Zumino-Witten models and path integrals.
The Wess-Zumino-Witten (WZW) model is a 2 dimensional conformal field theory (CFT) where the field takes values in a Lie group G or its coset space. For a compact group G this CFT is rational and its cosets G/H include for instance all unitary rational CFTs (e.g. the two dimensional Ising model). WZW model has a formal path integral...

N = 1 Super Topological Recursion.
A concrete relation between topological recursion and (modules of) the Virasoro algebra is well understood from the perspective of Airy structures. In fact, the notion of Airy structures plays an important role to generalise into the higher-rank setting, i.e. higher-ramified spectral curves and W-algebras of higher rank. Now, an intereseting question is:...

L-functions, automorphic spectra, and the conformal bootstrap.
Recently, a close parallel emerged between the spectral theory of automorphic forms and conformal field theory in general dimension. I will review this connection and explain how it can be leveraged to prove new results in number theory and spectral geometry using ideas borrowed from the conformal bootstrap. In particular, I...

Topological recursion and irregular conformal block via Painleve and WKB
Abstract: We will compare topological recursion and irregular conformal blocks, focusing on the Painlevé I equation. If time permits, we will also discuss a relation between the Heun accessory parameter with irregular singularities and the Voros periods.
This talk is based on joint work with N. Iorgov, O. Lisovyy,...

Fool’s crowns, Schwarzian, and topological recursion.
For a Riemann surface with holes, we propose a variant of the action on a circumference-P boundary component with n bordered cusps attached (a “fool’s crown”) that is decoration-independent and generates finite volumes V crown of the corresponding moduli spaces when integrated against the volume n,P form obtained by inverting the...

The double-scaled SYK model and Weil-Petersson volumes.
Okuyama expressed correlators in the double-scaled SYK model in terms of q-dependent polynomials arising from topological recursion on a particular spectral curve. He claimed that these polynomials recover the Weil-Petersson volumes studied by Mirzakhani in the limit as q approaches 1. In this talk, we discuss one-and-a-bit proofs of...

Boundary Liouville theory: from classical to quantum and back again.
In this talk we will discuss a geometric problem related to boundary Liouville CFT and closely related to uniformisation of open Riemann surfaces. Namely in a first part we will consider the classical problem of finding a conformal metric with constant scalar curvature, piecewise constant geodesic curvature and prescribed...

Three Theorems on the 6j symbol of the modular double of Uq(sl2(R)).
The modular double of Uq(sl2(R)) is an important quantum group in mathematical physics with a continuous spectrum of representations. The 6j symbol from its tensor structure, also known as the Racah-Wigner coe- ficients, were computed explicitly by Ponsot and Teschner. In this talk, I will present three theorems I proved...

Semiclassical Limit of Conformal Blocks, Nekrasov--Rosly--Shatashvili Relations, and the Trieste Formula for the Heun Equation.
This talk reviews recent advances in understanding the semiclassical limit of conformal blocks on the torus. Within this framework, we present ongoing work on the Nekrasov--Rosly--Shatashvili relations in gauge theory, their implications for semiclassical Liouville...

Conformal Bootstrap for boundary Liouville CFT.
In this talk, I will explain how to compute the Liouville correlation function for surfaces with boundary via the conformal bootstrap method. In the first part, I will explain my previous work establishing the integrability of Liouville CFT on the annulus. This result leveraged the known spectral resolution for the bulk Liouville theory and...
