Teleparallel gravity (TG) has significantly increased in popularity in recent decades, bringing
attention to Einstein's other theory of gravity. In this Review, we give a comprehensive …

Lovelock theory is a natural extension of Einstein theory of gravity to higher dimensions, and
it is of great interest in theoretical physics as it describes a wide class of models. In …

Under suitable assumptions on the boundary conditions, it is shown that there is a bijective
correspondence between equivalence classes of asymptotic reducibility parameters and …

We show that that four dimensional conformal gravity plus a simple Neumann boundary
condition can be used to get the semiclassical (or tree level) wavefunction of the universe of …

Gravitation theories selected by requiring that they have a unique anti–de Sitter vacuum with
a fixed cosmological constant are studied. For a given dimension d, the Lagrangians under …

All energy is gravitational energy. That is the consequence of the equivalence principle,
according to which gravity is the universal interaction. The physical charges of this …

We investigate a string-inspired dark energy scenario featuring a scalar field with a coupling
to the Gauss-Bonnet invariant. We discuss extensively the cosmological and astrophysical …

The null surfaces of a spacetime act as oneway membranes and can block information for a
corresponding family of observers (timelike curves). Since lack of information can be related …

We present a method for finding, in principle, all asymptotic gravitational charges. The basic
idea is that one must consider all possible contributions to the action that do not affect the …

The method of topological renormalization in anti–de Sitter (AdS) gravity consists in adding
to the action a topological term which renders it finite, defining at the same time a well-posed …
