Conformal geometry from entanglement

SciPost Physics
In a physical system with conformal symmetry, observables depend on cross-ratios, measures of distance invariant under global conformal transformations (conformal geometry for short).

Ricci Bi-Conformal Vector Fields on Siklos Spacetimes [PDF]

Mathematics Interdisciplinary Research
‎Ricci bi-conformal vector fields have find their place in geometry as well as in physical applications‎. ‎In this paper‎, ‎we consider the Siklos spacetimes and we determine all the Ricci bi-conformal vector fields on these spaces‎.

Conformal Coupling and Invariance in Different Dimensions

, 1994
Conformal transformations of the following kinds are compared: (1) conformal coordinate transformations, (2) conformal transformations of Lagrangian models for a D-dimensional geometry, given by a Riemannian manifold M with metric g of arbitrary ...

An Introduction to Conformal Ricci Flow [PDF]

, 2003
We introduce a variation of the classical Ricci flow equation that modifies the unit volume constraint of that equation to a scalar curvature constraint.

On conformal transformation of $\Xi$-curvature [PDF]

AUT Journal of Mathematics and Computing
In this paper, we study the conformal transformation of recent defined non-Riemannian curvature in Finsler Geometry, namely $\Xi$-curvature. Indeed, we obtain the necessary and sufficient condition under which the conformal transformation preserves the $\

The geometry of gauged (super)conformal mechanics

Journal of High Energy Physics, 2022
Motivated by recently explored examples, we undertake a systematic study of conformal invariance in one-dimensional sigma models where an isometry group has been gauged.

Non-Commutative Geometry and Twisted Conformal Symmetry

, 2005
The twist-deformed conformal algebra is constructed as a Hopf algebra with twisted co-product. This allows for the definition of conformal symmetry in a non-commutative background geometry.

Noncommutative Geometry and Conformal Geometry. III. Vafa-Witten Inequality and Poincar\'e Duality

, 2015
This paper is the the third part of a series of paper whose aim is to use of the framework of \emph{twisted spectral triples} to study conformal geometry from a noncommutive geometric viewpoint. In this paper we reformulate the inequality of Vafa-Witten \
