Lovelock Gravity |
In General > s.a. higher-order gravity
theories and types of higher-order theories.
* Idea: A higher-dimensional gravity
theory with higher-order curvature terms, which are considered important for the low-energy
action of string theories; Lovelock terms in the action consist of the dimensionally-extended
Euler densities, polynomial scalar densities in the Riemann curvature tensor with the property
that their Euler-Lagrange derivatives contain derivatives of the metric only up to second
order (generic polynomial scalar densities lead to Euler-Lagrange equations with derivatives
of the metric of order four).
* Properties: The theory is free from
ghosts; In these theories, gravity may travel faster or slower than light.
