A note on pure connection formalism for unimodular gravity and its possible generalisations
Alexey L. Smirnov
In this note, we consider the Henneaux-Teitelboim version of Unimodular Gravity (UG) and its deformations in the form of gauge theories with spontaneously broken diffeomorphism inv…
The initial data problem for a traversable wormhole with interacting mouths
Alexey L. Smirnov
In this study, we consider the time-symmetric initial data problem for GR minimally coupled with a phantom scalar field and a Maxwell field. The main focus is on initial data sets…
On the cosmological solutions in Weyl geometry
Victor A. Berezin, Vyacheslav I. Dokuchaev, Yury N. Eroshenko +1
We investigated the possibility of construction the homogeneous and isotropic cosmological solutions in Weyl geometry. We derived the self-consistency condition which ensures the c…
Quadratic Gravity, double layers and non-conservative energy-momentum tensor
Victor A. Berezin, Vyacheslav I. Dokuchaev, Yury N. Eroshenko +1
In the present paper we investigate the conservative conditions in Quadratic Gravity. It is shown explicitly that the Bianchi identities lead to the conservative condition of the l…
Traversable intra-Universe wormholes and timeholes in General Relativity: two new solutions
Alexey L. Smirnov
Using thin shell formalism we construct two solutions of intra-universe wormholes. The first model is a cosmological analog of the Aichelburg-Schein timehole, while another one is…
Interacting thin shells in the interior of a Reissner-Nordstrom black hole
Alexey L. Smirnov
In this paper we consider some applications of the extended Dray-t'Hooft-Redmount relation. In particular, using this relation, we study geometries of interacting thin shells near…
