Description
Let us consider Lovelock theory of gravity in higher dimensional spacetime and compactify extra dimmensions 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 dimmension of the internal space must be larger than or equal to six.
