Abstract This paper investigates some implications of mimetic gravity on the black hole thermodynamics. We begin with an analysis of the mimetic action and its relationship to the spacetime curvature, highlighting the field equations and their contri

In the context of f(Q) gravity, cosmological inflation takes a different turn. f(Q) gravity is a modified theory of gravity, where the Lagrangian is a function of the non-metricity scalar Q. f(Q) gravity theory is part of an extensive class of modifi

We show that perturbations of a scalar field in the background of the spherically symmetric black hole obtained with the Starobinsky-Bel-Robinson Gravity are unstable unless the dimensionless coupling β describing the compactification of M-theory is

If visible matter alone is present in the Universe, general relativity (GR) and its Newtonian weak field limit (WFL) cannot explain several pieces of evidence, from the largest to the smallest scales. The most investigated solution is the cosmologica

We study systems in arbitrary space-time dimensions where matter, deformed by TT‾-like irrelevant operators, is coupled to gravity in the Palatini formalism. The dynamically equivalent perspective is investigated, wherein the deformation transition
