We review the topic of 4D Einstein–Gauss–Bonnet (4DEGB) gravity, which has been the
subject of considerable interest over the past two years. Our review begins with a general …

Lanczos–Lovelock models of gravity represent a natural and elegant generalization of
Einstein's theory of gravity to higher dimensions. They are characterized by the fact that the …

A bstract Recently a Complexity-Action (CA) duality conjecture has been proposed, which
relates the quantum complexity of a holographic boundary state to the action of a Wheeler …

Recent times witnessed a significant interest in regularizing, a D → 4 D→ 4 limit, of EGB
gravity initiated by Glavan and Lin Phys. Rev. Lett. 124, 081301 (2020) by re-scaling GB …

We study properties of static, asymptotically AdS black holes in Lovelock gravity. Our main
result is a Smarr formula that gives the mass in terms of geometrical quantities together with …

We study several aspects of higher-order gravities constructed from general contractions of
the Riemann tensor and the metric in arbitrary dimensions. First, we use the fast …

We discuss the properties of Lorentzian wormholes in dilatonic Einstein-Gauss-Bonnet
theory in four spacetime dimensions. These wormholes do not need any form of exotic …

We explore the relation between positivity of the energy constraints in conformal field
theories and causality in their dual gravity description. Our discussion involves CFTs with …

We derive electrically charged black hole solutions of the Einstein-Gauss-Bonnet equations
with a nonlinear electrodynamics source in n (≥ 5) dimensions. The spacetimes are given …

A bstract We study certain bi-scalar-tensor theories emanating from conformal symmetry
requirements of Horndeski's four-dimensional action. The former scalar is a Galileon with …
