An information geometrical evaluation of Shannon information metrics on a discrete n-dimensional digital manifold [PDF]
Heliyon, 2023 The definition and nature of information have perplexed scientists due to its dual nature in measurements. The information is discrete and continuous when evaluated on a metric scale, and the Laplace-Beltrami operator and Gauss-Bonnet Theorem can map one

Born–Infeld black holes in 4D Einstein–Gauss–Bonnet gravity
European Physical Journal C: Particles and Fields, 2020 A novel four-dimensional Einstein-Gauss-Bonnet gravity was formulated by Glavan and Lin (Phys. Rev. Lett. 124:081301, 2020), which is intended to bypass the Lovelock’s theorem and to yield a non-trivial contribution to the four-dimensional gravitational ...

Gauss-Bonnet-Chern theorem and differential characters [PDF]
Results in Mathematics, 2017 In this paper we first prove that every differential character can be represented by differential form with singularities. Then we lift the Gauss-Bonnet-Chern theorem for vector bundles to differential characters.Comment: 11 pages.

Thermodynamic Phase Transition and Joule Thomson Adiabatic Expansion for dS/AdS Bardeen Black Holes with Consistent 4D Gauss-Bonnet Gravity [PDF]
Iranian Journal of Astronomy and Astrophysics, 2022 Instead of the work \cite{1} given by Glaven and Lin in which in according to the Lovelock theorem it is not applicable for all types of 4-dimensional curved spacetimes of Einstein Gauss Bonnet gravity, authors of the work \cite{2} applied breakdown of ...

Thin accretion disk signatures of scalarized black holes in Einstein-scalar-Gauss-Bonnet gravity
Physics Letters B, 2021 Einstein-scalar-Gauss-Bonnet gravity has recently been known to exhibit spontaneous scalarization. In the presence of the Gauss-Bonnet term the no-hair theorem can be evaded and novel black hole solutions with non-trivial scalar fields have been found ...

AdS/BCFT and Island for curvature-squared gravity
Journal of High Energy Physics, 2022 In this paper, we investigate AdS/BCFT for curvature-squared gravity. To warm up, we start with Gauss-Bonnet gravity. We derive the one point function of stress tensor and show that the central charge related to the norm of displacement operator is ...

Testing new massive conformal gravity with the light deflection by black hole
Nuclear Physics B, 2023 We study the weak gravitational lensing effect of Non-Bocharova-Bronnikov-Melnikov-Bekenstein (BBMB) black hole in new massive conformal gravity. We analyze the deflection angle of light caused by new massive conformal gravity by using the Gauss-Bonnet ...
