Crossing-symmetric twist field correlators and entanglement negativity in minimal CFTs
Journal of High Energy Physics, 2021 We study conformal twist field four-point functions on a ℤ N orbifold. We examine in detail the case N = 3 and analyze theories obtained by replicated N-times a minimal model with central charge c < 1.

On the phase space of free higher-spin theories and conformal transformations
Nuclear Physics B, 2017 We write a first order action for higher-spin fields and construct a canonical map to Fronsdal theory. The first-order description is defined over complex field configurations and has conformal invariance.

Complete minimal surfaces and harmonic functions [PDF]
, 2012 We prove that for any open Riemann surface N and any non constant harmonic function h : N → R, there exists a complete conformal minimal immersion X : N → R3 whose third coordinate function coincides with h.

The 't Hooft Model As A Hologram [PDF]
, 2009 We consider the 3d dual of 1+1 dimensional large-N_c QCD with quarks in the fundamental representation, also known as the 't Hooft model. 't Hooft solved this model by deriving a Schroedinger equation for the wavefunction of a parton inside the meson. In

Conformal Mapping in Linear Time [PDF]
Discrete & Computational Geometry, 2010 Given any $ε>0$ and any planar region $Ω$ bounded by a simple n-gon $P$ we construct a ($1 + ε)$-quasiconformal map between $Ω$ and the unit disk in time $C(ε)n$. One can take $ C(ε) = C + C \log (1/ε) \log \log (1/ε)$.

Conformal Mapping on Rough Boundaries I: Applications to harmonic problems
, 2004 The aim of this study is to analyze the properties of harmonic fields in the vicinity of rough boundaries where either a constant potential or a zero flux is imposed, while a constant field is prescribed at an infinite distance from this boundary.

On Riemannian manifolds endowed with a locally conformal cosymplectic structure
International Journal of Mathematics and Mathematical Sciences, 2005 We deal with a locally conformal cosymplectic manifold M(φ,Ω,ξ,η,g) admitting a conformal contact quasi-torse-forming vector field T. The presymplectic 2-form Ω is a locally conformal cosymplectic 2-form.

Worldsheet boundary conditions in Poisson-Lie T-duality [PDF]
, 2006 We apply canonical Poisson-Lie T-duality transformations to bosonic open string worldsheet boundary conditions, showing that the form of these conditions is invariant at the classical level, and therefore they are compatible with Poisson-Lie T-duality ...

How round is a protein? Exploring protein structures for globularity using conformal mapping.
Frontiers in Molecular Biosciences, 2014 We present a new algorithm that automatically computes a measure of the geometric difference between the surface of a protein and a round sphere. The algorithm takes as input two triangulated genus zero surfaces representing the protein and the round ...
