Intrinsic deformation theory of CR structures. (English) Zbl 1206.32015
Authors’ abstract: Let $$(V, \xi)$$ be a contact manifold and let $$J$$ be a strictly pseudoconvex CR-structure of hypersurface type on $$(V, \xi)$$; starting only from these data, we define and we investigate a differential graded Lie algebra which governs the deformation theory of $$J$$.
