Multidimensional Integrable Cosmological Models with Dynamical and Spontaneous Compactification

Abstract

Multidimensional cosmological models with $n(n>1)$ spaces of constant curvature are discussed classically and with respect to canonical quantization. These models are integrable in the case of Ricci flat internal spaces. For positive curvature in the external space we find exact solutions modelling dynamical as well as spontaneous compactification of internal spaces.
