概要

• 論文の詳細を見る

• The curvature singularity in viable f(R) gravity models is examined when the background density is dense. This singularity could be eliminated by adding the R^2 term in the Lagrangian. Some of cosmological consequences, in particular the source for the scalar mode of gravitational waves, are discussed.
