Exact models of pure radiation in R2 gravity for spatially homogeneous Shapovalov spacetimes type II
Abstract
Presented are exactly integrable models with pure radiation in R2 gravity with a cosmological constant, related to wave-like Shapovalov spacetimes type II. Spatially homogeneous models of Shapovalov spaces were considered. The obtained solutions belong to spaces of type III according to the Bianchi classification. For the models under consideration, exact solutions of the equations of motion of test particles are obtained in the Hamilton-Jacobi formalism.
