Quadratic Theory of Gravity with a Scalar Field and Type I Shapovalov Wave Spacetimes
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 relativity. The theory of gravity under consideration can effectively describe the early stages of t...
