Geodesic Warps by Conformal Mappings [PDF]

open access: yesInternational Journal of Computer Vision, 2012
In recent years there has been considerable interest in methods for diffeomorphic warping of images, with applications e.g.\ in medical imaging and evolutionary biology. The original work generally cited is that of the evolutionary biologist D'Arcy Wentworth Thompson, who demonstrated warps to deform images of one species into another.

Correlation functions at the bulk point singularity from the gravitational eikonal S-matrix

open access: yesJournal of High Energy Physics, 2019
The bulk point singularity limit of conformal correlation functions in Lorentzian signature acts as a microscope to look into local bulk physics in AdS.

Proposed single-zone map projection system for Turkey

open access: yesReports on Geodesy and Geoinformatics, 2022
The coordinate base of the maps or sheets produced is the Universal Transversal Mercator (UTM) conformal projection, and it is not possible to work in a single coordinate system in Turkey.

Mapping chromatin conformation [PDF]

open access: yesF1000 Biology Reports, 2010
Chromatin conformation capture (3C) and related techniques have become well-established methods to examine which distal DNA sequences are spatially located close to a locus of interest. Hi-C is a new addition to the growing set of 3C-based techniques that has extended the approach to a genome-wide analysis of nuclear chromatin using high-throughput DNA

Universal spinning Casimir equations and their solutions

open access: yesJournal of High Energy Physics, 2023
Conformal blocks are a central analytic tool for higher dimensional conformal field theory. We employ Harish-Chandra’s radial component map to construct universal Casimir differential equations for spinning conformal blocks in any dimension d of ...

The hypersurfaces with conformal normal Gauss map in Hn+1 and S1n+1

open access: yesAnais da Academia Brasileira de Ciências, 2008
In this paper, we introduce the fourth fundamental forms for hypersurfaces in Hn+1 and space-like hypersurfaces in S1n+1, and discuss the conformality of the normal Gauss map of the hypersurfaces in Hn+1 and S1n+1.

Crossing-symmetric twist field correlators and entanglement negativity in minimal CFTs

open access: yesJournal 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

open access: yesNuclear 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.

Conformal Mapping in Linear Time [PDF]

open access: yesDiscrete & 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)$.
