Manifolds admitting stable forms. (English) Zbl 1212.53051
A \(k\)-form \(\gamma \) on a (real or complex) vector space \(V^n\) is stable if its orbit \(GL(n)(\gamma)\) is open in \({\Lambda }^k(V^n)^*\); stable forms are multi-symplectic. A method presented in the paper allows to classify stable forms on real \(n\)-dimensional space and find their automorphism groups. Some necessary conditions, and also sufficient conditions for a manifold to admit a stable form are given, some interesting examples and consequences are presented.
