Type I Shapovalov wave spacetimes in the Brans-Dicke scalar-tensor theory of gravity field equations of the Brans-Dicke scalar-tensor
theory of
gravity lead to exact solutions for type I
Kinetic scalar curvature extended f(R) gravity modified f(R)
gravity, and we show the mathematical equivalence of the two
theories.
