On stability of compactified Lovelock gravity with symmetric Riemann manifolds
- Dr. Keisuke OHASHI
Let us consider Lovelock theory of gravity in higher dimensional spacetime and compactify extra dimensions with a variety of symmetric Riemann manifolds. In those cases, stability of size moduli of such internal spaces need non-vanishing higher-order Lovelock terms higher than the quadratic term. That is, a dimension of the internal space must be larger than or equal to six.
