c-theorem of the entanglement entropy

Journal of High Energy Physics, 2018
We holographically investigate the renormalization group flow in a two-dimensional conformal field theory deformed by a relevant operator. If the relevant operator allows another fixed point, the UV conformal field theory smoothly flows to a new IR ...

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 gravitational theories in Barthel–Kropina-type Finslerian geometry, and their cosmological implications

European Physical Journal C: Particles and Fields, 2023
We consider dark energy models obtained from the general conformal transformation of the Kropina metric, representing an $$(\alpha , \beta )$$ ( α , β ) -type Finslerian geometry, constructed as the ratio of the square of a Riemannian metric $$\alpha ...

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 $\

Notes on symmetric conformal geometries [PDF]

Archivum Mathematicum, 2015
In this article, we summarize the results on symmetric conformal geometries. We review the results following from the general theory of symmetric parabolic geometries and prove several new results for symmetric conformal geometries. In particular, we show that each symmetric conformal geometry is either locally flat or covered by a pseudo-Riemannian ...

Quantum gravity from Weyl conformal geometry

European Physical Journal C: Particles and Fields
We review recent developments in physical implications of Weyl conformal geometry. The associated Weyl quadratic gravity action is a gauge theory of the Weyl group of dilatations and Poincaré symmetry.

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.
