Numerical conformal mapping onto a rectangle with applications to the solution of Laplacian problems [PDF]
, 1988 Let F be the function which maps conformally a simple-connected domain onto a rectangle R, so that four specified points on are mapped Ω∂respectively onto the four vertices of R. In this paper we consider the problem of approximating the conformal map F,

Isomonodromic deformations and conformal field theory with W-symmetry [PDF]
, 2018 The correspondence between isomonodromic deformations and conformal field theories with W-symmetry relates isomonodromic tau-functions to linear combinations of conformal blocks of the W-algebras.

4d/2d Correspondence: Instantons and W-Algebras [PDF]
, 2012 In this thesis, we study the 4d/2d correspondence of Alday-Gaiotto-Tachikawa, which relates the class of 4-dimensional N=2 gauge theories (theories of class S) to a 2-dimensional conformal field theory. The 4d gauge theories are obtained by compactifying

Cut-touching linear functionals in the conformal bootstrap
Journal of High Energy Physics, 2017 The modern conformal bootstrap program often employs the method of linear functionals to derive the numerical or analytical bounds on the CFT data. These functionals must have a crucial “swapping” property, allowing to swap infinite summation with the ...

Modular differential equations with movable poles and admissible RCFT characters
Journal of High Energy Physics, 2023 Studies of modular linear differential equations (MLDE) for the classification of rational CFT characters have been limited to the case where the coefficient functions (in monic form) have no poles, or poles at special points of moduli space.

Crossing, modular averages and N ↔ k in WZW models
Journal of High Energy Physics, 2019 We consider the construction of genus zero correlators of SU(N ) k WZW models involving two Kac-Moody primaries in the fundamental and two in the anti-fundamental representation from modular averaging of the contribution of the vacuum conformal block. We

Conformal four-point correlation functions from the operator product expansion
Journal of High Energy Physics, 2020 We show how to compute conformal blocks of operators in arbitrary Lorentz representations using the formalism described in [1, 2] and present several explicit examples of blocks derived via this method.

Journal of High Energy Physics, 2019 We study the Virasoro conformal block decomposition of the genus two partition function of a two-dimensional CFT by expanding around a ℤ3-invariant Riemann surface that is a three-fold cover of the Riemann sphere branched at four points, and explore ...

The analytic bootstrap equations of non-diagonal two-dimensional CFT
Journal of High Energy Physics, 2018 Under the assumption that degenerate fields exist, diagonal CFTs such as Liouville theory can be solved analytically using the conformal bootstrap method. Here we generalize this approach to non-diagonal CFTs, i.e.

Bound on asymptotics of magnitude of three point coefficients in 2D CFT
Journal of High Energy Physics, 2020 We use methods inspired from complex Tauberian theorems to make progress in understanding the asymptotic behavior of the magnitude of heavy-light-heavy three point coefficients rigorously. The conditions and the precise sense of averaging, which can lead
