Аннотация:A theory of interacting gravity, vector and antisymmetric third-rank tensor fields with the spontaneous compactification solution of Freund-Rubin type in seven-dimensional space-time is presented. A class of models is studied, which admit Freund-Rubin type of compactification and, at the same time, possess nontrivial solutions for the vector field. We obtain the mass spectrum of fourdimensional modes, which appears after dimensional reduction. We also demonstrate the absence of tachyon modes and the presence of additional massless vector and scalar modes.
