Description: Exact models of primordial gravitational waves in the Bianchi type-III universe were constructed on the basis of the quadratic theory of gravity with a scalar field and pure radiation in Shapovalov wa ... More
Add   Quadratic theory of gravity with a scalar field and type I Shapovalov wave spacetimes
Authors: Osetrin, Konstantin E. | Kirnos, Ilya V. | Filippov, Altair
Source: Universe. 2022. Vol. 8, № 12. P. 664 (1-15)
Type: статьи в журналах
Date: 2022
Description: 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 the general theory of ... More
Add   Type I Shapovalov wave spacetimes in the Brans-Dicke scalar-tensor theory of gravity
Authors: Osetrin, Konstantin E. | Filippov, Altair | Kirnos, Ilya V. | Osetrin, Evgeny
Source: Symmetry. 2022. Vol. 14, № 12. P. 2636 (1-12)
Type: статьи в журналах
Date: 2022
Description: Exact solutions for Shapovalov wave spacetimes of type I in Brans-Dicke's scalar-tensor theory of gravity are constructed. Shapovalov wave spacetimes describe gravitational wave models that allow for ... More
