Various results about continuous and compact embeddings are … WebHow do you prove that the Sobolev space Hs(Rn) is an algebra if s > n 2, i.e. if u, v are in Hs(Rn), then so is uv? Actually I think we should also have ‖uv‖s ≤ C‖u‖s‖v‖s. Recall that ‖f‖s = ‖(1 + η 2)s / 2ˆf(η)‖, the norm on Hs(Rn). This is an exercise from Taylor's book, Partial differential equations I. partial-differential-equations

WebThe paper provides new characterisations of generators of cosine functions and C 0-groups on UMD spaces and their applications to some classical problems in cosine function theory. In particular, we show that on UMD spaces, generators of cosine functions and C 0-groups can be characterised by means of a complex inversion formula. This allows us to provide … WebWe obtain improved fractional Poincaré inequalities in John domains of a metric space endowed with a doubling measure under some mild regularity conditions on the measure .
