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 …

We review nonsingular static, spherically symmetric solutions of general relativity with
minimally coupled scalar fields. Considered are wormholes and regular black holes (BHs) …

In this work, we construct traversable wormhole geometries in the context of f (R) modified
theories of gravity. We impose that the matter threading the wormhole satisfies the energy …

This article evaluates the stability constraints of higher-dimensional geometry of thin-shell
wormholes developed from the two equivalent copies of inner and outer d-dimensional …

Traversable wormholes, tunnel-like structures introduced by Morris and Thorne [Am. J. Phys.
56 (1988) 395], have a significant role in connection of two different spacetimes or two …

In this study, we explore the new wormhole solutions in the framework of new modified f (R,
ℒ m) gravity. To obtain a characteristic wormhole solution, we use anisotropic matter …

In this paper, we explore higher-dimensional asymptotically flat wormhole geometries in the
framework of Gauss-Bonnet (GB) gravity and investigate the effects of the GB term, by …

In this paper, we construct a thin-shell wormhole (TSW) in 4 D Einstein–Gauss–Bonnet
gravity (EGB) and examine the stability condition of the wormhole (WH) by using the linear …

We present a new cubic theory of gravity in five dimensions which has second-order traced
field equations, analogous to BHT new massive gravity in three dimensions. Moreover, for …

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 …
