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 …

In this Letter we present a general covariant modified theory of gravity in D= 4 spacetime
dimensions which propagates only the massless graviton and bypasses Lovelock's theorem …

A bstract We comment on the recently introduced Gauss-Bonnet gravity in four dimensions.
We argue that it does not make sense to consider this theory to be defined by a set of D→ 4 …

Recently a non-trivial 4-dimensional theory of gravity that claims to circumvent Lovelock's
theorem and avoid Ostrogradsky instability was formulated in Glavan and Lin (2020)[1]. This …

Recently a D-dimensional regularization approach leading to the non-trivial (3+ 1)(3+ 1)-
dimensional Einstein–Gauss–Bonnet (EGB) effective description of gravity was formulated …

Recently, a novel 4D Einstein–Gauss–Bonnet gravity was formulated by Glavan and Lin
(Phys Rev Lett 124 (8): 081301, 2020). Although whether the theory is well defined is …

Recently there has been a surge of interest in regularizing, a D→ 4 limit of, the Einstein-
Gauss-Bonnet (EGB) gravity, and the resulting regularized 4D EGB gravity has nontrivial …

We propose a regularization procedure for the novel Einstein-Gauss-Bonnet theory of
gravity, which produces a set of field equations that can be written in closed form in four …

The discovery of new four-dimensional black hole solutions presents a new approach to
understand the Gauss-Bonnet gravity in low dimensions. In this paper, we test the Gauss …

Recently, a novel 4D Einstein–Gauss–Bonnet gravity has been proposed by Glavan and Lin
(2020 Phys. Rev. Lett. 124 081301) by rescaling the coupling $\alpha\to\alpha/(D-4) $ and …
