Abstract:
A Sobolev-type embedding theorem is established, which differs from classical statements in that the assumptions are imposed on linear combinations of the form ∑ajDαjfj with different functions fj and different multi-indices αj. It is applied to a classification problem for spaces of smooth functions generated by finite collections of differential expressions.
Keywords:
space of smooth functions, isomorphism, Sobolev embedding.
