In arbitrary higher dimension, we consider the combination of Lovelock gravity alongside a
scalar-tensor action built out of higher order operators and Euler densities. The latter action …

We show via an explicit construction how an infinite tower of higher-curvature corrections
generically leads to a resolution of the Schwarzschild singularity in any spacetime …

A bstract We analyse in all generality beyond Horndeski theories of shift symmetry in a static
and spherically symmetric spacetime. By introducing four auxiliary functions, we write the …

We show that the scalar-tensor theory that arises in a rigorous D→ 3 limit of Lovelock gravity
up to cubic order admits a holographic c-theorem and verify that the value of the c-function at …

Hyperbolic vacuum black holes in Lovelock gravity theories of odd order N, in which N
denotes the order of higher-curvature corrections, are known to have the so-called isolated …

Recently, it was discovered that lower-dimensional versions of Lovelock gravity exist as
scalar-tensor theories that are examples of Horndeski gravity. We study the thermodynamics …

General Relativity allows for a unique black hole solution, characterized by its mass M,
angular momentum J, and electric charge Q. Black holes in General Relativity are thus said …

We give a microscopic derivation of the semi-classical entropy of static black holes in 3d
Lovelock gravities, which are certain 3d Horndeski theories that were recently discovered …

In this thesis, we discuss Gauss-Bonnet theories of gravity, with a focus on the topic of 4D
Einstein-Gauss-Bonnet gravity, which has been the subject of considerable interest over the …
