Abstract

A CR manifold M is a differentiable manifold together with a complex subbundle of the complexification of its tangent bundle, which is formally integrable and has zero intersection with its conjugate bundle. A fundamental invariant of a CR manifold M is its vector-valued Levi form. A Levi non degenerate CR manifold of order k≥1 has non degenerate Levi form in a higher order sense. For a (locally) homogeneous manifold Levi non degeneracy of order k can be described in terms of its CR algebra, i.e. a pair of Lie algebras encoding the structure of (locally) homogeneous CR manifolds. I will give an introduction to these topics presenting some recent results
