The classical generalization of general relativity is considered as the gravitational alternative
for a unified description of the early-time inflation with late-time cosmic acceleration. The …

It has been suggested that a possible candidate for the present accelerated expansion of the
Universe is “phantom energy”. The latter possesses an equation of state of the form ω≡ p/ρ< …

Originally proposed as a tool for teaching the general theory of relativity, wormholes are
today approached in many different ways and are seeing as an efficient alternative for …

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 work, we analyse static spherically symmetric solutions in the framework of mimetic
gravity, an extension of general relativity where the conformal degree of freedom of gravity is …

This manuscript aims to establish the gravitational junction conditions for the f (G, T) gravity.
In this gravitational theory, f is an arbitrary function of Gauss-Bonnet invariant G and the …

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 …

In this paper, we study spherically symmetric traversable wormholes (WHs) in the torsion
and matter coupling gravity formalism. We have thoroughly investigated the field equations …

This analysis explores the new wormhole (WH) solution in the background of teleparallel
gravity with minimal matter coupling. To complete this study, we consider the conformal …

Properties of n (≥ 5)-dimensional static wormhole solutions are investigated in Einstein-
Gauss-Bonnet gravity with or without a cosmological constant Λ. We assume that the …
