Effects of a Wess-Zumino term in the theory of a d=11 supergravity
Kogan Ya. I. , Morozov A. Yu.
The action of a d = 11 supergravity is renormalization-invariant in up to seventh-order perturbation theory because of a topological term in this action. A mechanism for the compactification Μ"—>(4D space) XS7 is also discussed.
