Abstract:

One clarifies the relationship between the two most standard ways to measure the order of contact of $q$-dimensional complex varieties with a real hypersurface. These invariants play an important role in the Kohn algorithm for the Neumann problem for $(p, q)$-forms. Joint work with Andreea Nicoară.
