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 …

Abstract The Chern–Simons (CS) form evolved from an obstruction in mathematics into an
important object in theoretical physics. In fact, the presence of CS terms in physics is more …

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 …

This is intended as a broad introduction to Chern-Simons gravity and supergravity. The
motivation for these theories lies in the desire to have a gauge invariant system--with a fiber …

In this paper, we consider third-order Lovelock gravity with a cosmological constant term in
an n-dimensional spacetime M 4× K n-4, where K n-4 is a constant curvature space. We …

Chern–Simons models for gravity are interesting because they provide a truly gauge-
invariant action principle in the fiber-bundle sense. So far, their main drawback has largely …

Mass and other conserved Noether charges are discussed for solutions of gravity theories
with locally anti–de Sitter (AdS) asymptotics in 2 n dimensions. The action is supplemented …

Asymptotically locally AdS black hole geometries of dimension d>~ 3 are studied for
nontrivial topologies of the transverse section. These geometries are static solutions of a set …

We compare the metric and the Palatini formalism to obtain the Einstein equations in the
presence of higher-order curvature corrections that consist of contractions of the Riemann …

It is shown that using a specific semigroup, the S-expansion of the AdS Lie algebra leads to
a generalization of the so (D− 1, 1)⊕ so (D− 1, 2) algebras, which are called generalized …
