We consider the monodromy problem for the four-punctured sphere in which the character of one composite monodromy is fixed, by looking at the expansion of the accessory parameter in the modulus x directly, without taking the limit of the quantum conformal blocks for an infinite central charge. The integrals that appear in the expansion of the Volterra equation involve products of two hypergeometric functions to first order and up to four hypergeometric functions to second order. It is shown…

A note on the Virasoro blocks at order 1 / c

We derive an explicit expression for the 1 / c contribution to the Virasoro blocks in 2D CFT in the limit of large c with fixed values of the operators’ dimensions. We follow the direct approach of

Higher-point conformal blocks and entanglement entropy in heavy states

A bstractWe consider conformal blocks of two heavy operators and an arbitrary number of light operators in a (1+1)-d CFT with large central charge. Using the monodromy method, these higher-point

Torus classical conformal blocks

After deriving the classical Ward identity for the variation of the action under a change of the modulus of the torus, we map the problem of the sphere with four sources to the torus. We extend the

Coulomb gas integrals, classical conformal blocks and Richardson–Gaudin models

Virasoro conformal blocks are universal ingredients of correlation functions of two-dimensional CFTs with Virasoro symmetry. It is acknowledged that in the (classical) limit of large central charge

Accessory parameters in confluent Heun equations and classical irregular conformal blocks

Classical Virasoro conformal blocks are believed to be directly related to accessory parameters of Floquet type in the Heun equation and some of its confluent versions. We extend this relation to

Classical conformal blocks, Coulomb gas integrals and Richardson-Gaudin models

Abstract Virasoro conformal blocks are universal ingredients of correlation functions of two-dimensional conformal field theories (2d CFTs) with Virasoro symmetry. It is acknowledged that in the

Kerr-de Sitter quasinormal modes via accessory parameter expansion

A bstractQuasinormal modes are characteristic oscillatory modes that control the relaxation of a perturbed physical system back to its equilibrium state. In this work, we calculate QNM frequencies



Accessory parameters for Liouville theory on the torus

A bstractWe give an implicit equation for the accessory parameter on the torus which is the necessary and sufficient condition to obtain the monodromy of the conformal factor. It is shown that the
