The varieties of Heisenberg vertex operator algebras

open access: yes, 2016
For a vertex operator algebra $V$ with conformal vector $\omega$, we consider a class of vertex operator subalgebras and their conformal vectors.

Dipole-magnet field models based on a conformal map

open access: yesPhysical Review Special Topics. Accelerators and Beams, 2012
In general, generation of charged-particle transfer maps for conventional iron-pole-piece dipole magnets to third and higher order requires a model for the midplane field profile and its transverse derivatives (soft-edge model) to high order and ...

A Formula of Packing Pressure of a Factor Map

open access: yesEntropy, 2017
In this paper, using the notion of packing pressure, we show a formula of packing pressure of a factor map. We also give an application in conformal repellers.

Celestial diamonds: conformal multiplets in celestial CFT

open access: yesJournal of High Energy Physics, 2021
We examine the structure of global conformal multiplets in 2D celestial CFT. For a 4D bulk theory containing massless particles of spin s = 0 1 2 1 3 2 2 $$ \left\{0,\frac{1}{2},1,\frac{3}{2},2\right\} $$ we classify and construct all SL(2,ℂ) primary ...

Singular Laplacian Growth

open access: yes, 1997
The general equations of motion for two dimensional Laplacian growth are derived using the conformal mapping method. In the singular case, all singularities of the conformal map are on the unit circle, and the map is a degenerate Schwarz-Christoffel map.

Selecting Map Projections in Minimizing Area Distortions in GIS Applications

open access: yesSensors, 2008
Varioussoftware for Geographical Information Systems (GISs) have been developed and used in many different engineering projects. In GIS applications, map coverage is important in terms of performing reliable and meaningful queries. Map projections can be

Numerical Conformal Mapping

open access: yesNotices of the American Mathematical Society
Most conformal maps cannot be found analytically, so when computers began to appear in the 1950s and 1960s, the field of numerical conformal mapping was born. The availability of so many tools for numerical conformal mapping may suggest that the problem is easy, but in fact there are challenges.

`Conformal Theories - AdS Branes' Transform, or One More Face of AdS/CFT

open access: yes, 2003
The AdS/CFT transformation relates two nonlinear realizations of (super)conformal groups: their realization in the appropriate field theories in Minkowski space with a Goldstone dilaton field and their realization as (super)isometry groups of AdS (super ...

Some results of the f-biharmonic maps and applications

open access: yesArab Journal of Mathematical Sciences, 2018
In this paper, we give some properties of the f-biharmonic maps, in the particular case represented by conformal maps between equidimensional manifolds.
