de Sitter stability in theories with second order curvature terms |
Abstract _ |
A general form of second order curvature corrections leads to forth-order equations of motion. This may cause some solution of unperturbed equations to be unstable. We derive conditions which ensure that de Sitter solution in General Relativity remains stable with respect to second order curvature terms. |
