An exact model of a gravitational wave in the Bianchi III universe based on Shapovalov II wave spacetime and the quadratic theory of gravity

Konstantin Osetrin, Ilya Kirnos, Evgeny Osetrin

Exact models of primordial gravitational waves in the Bianchi type III universe are constructed on the basis of the quadratic theory of gravity with a scalar field and pure radiati…

Type I Shapovalov wave spacetimes in the Brans-Dicke scalar-tensor theory of gravity

Konstantin Osetrin, Altair Filippov, Ilya Kirnos +1

Exact solutions for Shapovalov wave spacetimes of type I in the scalar-tensor theory of gravity of Brans-Dicke are constructed. Shapovalov's wave spacetimes describe gravitational-…

Quadratic theory of gravity with a scalar field and type I Shapovalov wave spacetimes

Konstantin Osetrin, Ilya Kirnos, Altair Filippov

For the quadratic theory of gravity with a scalar field, exact solutions are found for gravitational-wave models in Shapovalov~I~type spacetimes, which do not arise in models of th…

New features of flat (4+1)-dimensional cosmological model with a perfect fluid in Gauss-Bonnet gravity

I. V. Kirnos, S. A. Pavluchenko, A. V. Toporensky

We investigated a flat multidimensional cosmological model in Gauss-Bonnet gravity in presence of a matter in form of perfect fluid. We found analytically new stationary regimes (t…

The nature of singularity in multidimensional anisotropic Gauss-Bonnet cosmology with a perfect fluid

I. V. Kirnos, A. N. Makarenko, S. A. Pavluchenko +1

We investigate dynamics of (4+1) and (5+1) dimensional flat anisotropic Universe filled by a perfect fluid in the Gauss-Bonnet gravity. An analytical solutions valid for particular…
