Exact model of gravitational wave and pure radiation
Konstantin E. Osetrin, Vladimir Y. Epp, Altair E. Filippov
An exact non-perturbative model of a gravitational wave with pure radiation is constructed. It is shown that the presence of dust matter in this model contradicts Einstein's field…
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…
Wave-like exact models with symmetry of spatial homogeneity in the quadratic theory of gravity with a scalar field
K. E. Osetrin, I. V. Kirnos, E. K. Osetrin +1
Exact solutions are obtained in the quadratic theory of gravity with a scalar field for wave-like models of space-time with spatial homogeneity symmetry and allowing the integratio…
Exact models of pure radiation in R^2 gravity for spatially homogeneous Shapovalov spacetimes type II
Konstantin Osetrin, Altair Filippov, Evgeny Osetrin
Presented are exactly integrable models with pure radiation in R^2 gravity with a cosmological constant, related to wave-like Shapovalov spacetimes type II. Spatially homogeneous m…
Wave-like spatially homogeneous models of Stackel spacetimes (2.1) type in the scalar-tensor theory of gravity
K. Osetrin, A. Filippov, E. Osetrin
Six exact solutions are obtained in the general scalar-tensor theory of gravity related to spatially homogeneous wave-like models of the Universe. Wave-like space-time models allow…
