A sharp higher order Sobolev embedding

Functional Analysis 2024-11-18 v1

Abstract

We obtain sharp embeddings from the Sobolev space W0k,2(1,1)W^{k,2}_0(-1,1) into the space L1(1,1)L^1(-1,1) and determine the extremal functions. This improves on a previous estimate of the sharp constants of these embeddings due to Kalyabin.
