Entire Scalar Curvature Flow and Hypersurfaces of Constant Scalar Curvature in Minkowski Space [PDF]

Methods and Applications of Analysis, 2009
We prove existence in the Minkowski space of entire spacelike hypersurfaces with constant negative scalar curvature and given set of lightlike directions at infinity; we also construct the entire scalar curvature flow with prescribed set of lightlike directions at infinity, and prove that the flow converges to a spacelike hypersurface with constant ...

Erratum to: Total Scalar Curvature and Harmonic Curvature [PDF]

Taiwanese Journal of Mathematics, 2016
It has been realized that the proof of Theorem 5.1 in Section 5 is imcomplete. It was pointed out by Professor Jongsu Kim and Israel Evangelista.

O(p + 1) x O(p + 1)-Invariant hypersurfaces with zero scalar curvature in euclidean space

Anais da Academia Brasileira de Ciências, 2000
We use equivariant geometry methods to study and classify zero scalar curvature O(p + 1) x O(p + 1)-invariant hypersurfaces in R2p+2 with p > 1.

Kropina Metrics with Isotropic Scalar Curvature via Navigation Data

Mathematics
Through an interesting physical perspective and a certain contraction of the Ricci curvature tensor in Finsler geometry, Akbar-Zadeh introduced the concept of scalar curvature for the Finsler metric.

Non-minimal two-loop inflation

Physics Letters B, 2015
We investigate the chaotic inflationary model using the two-loop effective potential of a self-interacting scalar field theory in curved spacetime. We use the potential which contains a non-minimal scalar curvature coupling and a quartic scalar self ...

Kinetic scalar curvature extended f(R) gravity

Nuclear Physics B, 2018
In this work we study a modified version of vacuum f(R) gravity with a kinetic term which consists of the first derivatives of the Ricci scalar. We develop the general formalism of this kinetic Ricci modified f(R) gravity and we emphasize on cosmological
