%0 Journal Article %T On sharp constants in one-dimensional embedding theorems of arbitrary order %A Alexander I. Nazarov %J Mathematics %D 2013 %I arXiv %X We discuss the problem where the extremal function in embedding theorem of some (generally speaking, non-integer) order is the constant function. We obtain the necessary and sufficient conditions of this. %U http://arxiv.org/abs/1308.2259v1
