Discrete Schemes for Gaussian Curvature and Their Convergence
Discrete Gaussian curvature discrete mean curvature geometric
2012/8/7
In this paper, several discrete schemes for Gaussian curvature are sur-
veyed. The convergence property of a modi痚d discrete scheme for the
Gaussian curvature is proved. Furthermore, a new discrete ...
Full nonlinear growing and decaying modes of superhorizon curvature perturbations
Full nonlinear growing decaying modes
2010/11/30
We clarify the behavior of curvature perturbations in a nonlinear theory in case the inflaton temporarily stops during inflation. We focus on the evolution of curvature perturbation on superhorizon sc...
All Bulk and Boundary Unitary Cubic Curvature Theories in Three Dimensions
All Bulk and Boundary Unitary Cubic Curvature Theories Three Dimensions
2010/11/30
We construct all the bulk and boundary unitary cubic curvature parity invariant gravity theories in three dimensions in (anti)-de Sitter spaces. For bulk unitarity, our construction is based on the p...

Algebraic classification of spacetimes discriminating scalar curvature invariants
2010/11/30
The Weyl and Ricci tensors can be algebraically classified in a Lorentzian spacetime of arbitrary dimensions using alignment theory. Used in tandem with the boost weight decomposition and curvature op...
