SPHERICAL SYMMETRIC SOLUTIONS OF F(R) GRAVITY WITH A KINETIC CURVATURE SCALAR
Chervon S.V., Fabris J.C., Fomin I.V.
We consider modified f(R) gravity with a kinetic curvature scalar as a chiral self-gravitating model in a spherically symmetric spacetime. Most attention devoted to finding solutions for special case of scaling transformation when modified gravity transforms to Einstein frame from Jordan one. We proposed the method of determination of kinetic function for given scalar field dependence on space coordinate. New classes of solutions are found for special choice of f(R) function.
