Stable exponential cosmological solutions with two factor spaces in the Einstein-Gauss-Bonnet model with a $Λ$ -term

V. D. Ivashchuk, A. A. Kobtsev

We study $D$ -dimensional Einstein-Gauss-Bonnet gravitational model including the Gauss-Bonnet term and the cosmological term $Λ$ . We find a class of solutions with exponential time…

Nonlinear electrodynamics, regular black holes and wormholes

K. A. Bronnikov

We consider spherically symmetric configurations in general relativity, supported by nonlinear electromagnetic fields with gauge-invariant Lagrangians depending on the single invar…

Inhomogeneous compact extra dimensions

K. A. Bronnikov, R. I. Budaev, A. V. Grobov +2

We show that an inhomogeneous compact extra space possesses two necessary features --- their existence does not contradict the observable value of the cosmological constant $Λ_{4}$ i…

Dyonic configurations in nonlinear electrodynamics coupled to general relativity

K. A. Bronnikov

We consider static, spherically symmetric configurations in general relativity, supported by nonlinear electromagnetic fields with gauge-invariant Lagrangians depending on the sing…

Wormholes with fluid sources: A no-go theorem and new examples

K. A. Bronnikov, K. A. Baleevskikh, M. V. Skvortsova

For static, spherically symmetric space-times in general relativity (GR), a no-go theorem is proved: it excludes the existence of wormholes with flat and/or AdS asymptotic regions…

Stable exponential cosmological solutions with zero variation of $G$ and three different Hubble-like parameters in the Einstein-Gauss-Bonnet model with a $Λ$ -term

K. K. Ernazarov, V. D. Ivashchuk

We consider a $D$ -dimensional gravitational model with a Gauss-Bonnet term and the cosmological term $Λ$ . We restrict the metrics to diagonal cosmological ones and find for certain…

On wormholes with long throats and the stability problem

K. A. Bronnikov, P. A. Korolyov

We construct explicit examples of globally regular static, spherically symmetric solutions of general relativity with a phantom scalar field as the source of gravity, describing tr…

Stable exponential cosmological solutions with zero variation of G in the Einstein-Gauss-Bonnet model with a Lambda-term

K. K. Ernazarov, V. D. Ivashchuk

A D-dimensional gravitational model with a Gauss-Bonnet term and the cosmological term Lambda is considered. By assuming diagonal cosmological metrics, we find, for certain fine-tu…

Duality between k-essence and Rastall gravity

Kirill A. Bronnikov, Julio C. Fabris, Oliver F. Piattella +2

The k-essence theory with a power-law function of $(\partial ϕ)^{2}$ and Rastall's non-conservative theory of gravity with a scalar field are shown to have the same solutions for the…

Dilatonic dyon-like black hole solutions in the model with two Abelian gauge fields

M. E. Abishev, K. A. Boshkayev, V. D. Ivashchuk

Dilatonic black hole dyon-like solutions in the gravitational $4 d$ model with a scalar field, two 2-forms, two dilatonic coupling constants $λ_{i} \neq = 0$ , $i = 1, 2$ , obeying $λ_1 \ne…
