Estimates on translations and Taylor expansions in fractional Sobolev spaces
In this paper we study how the (normalised) Gagliardo semi-norms [u]<sub>Ws,p(Rn)</sub> control translations. In particular, we prove that ||u(·+y)−u ||<sub>Lp(Rn)</sub> ≤ C[u]<sub>Ws,p(Rn)</sub> |y| <sup>s</sup> for n ≥ 1, s ∈ [0, 1] and p ∈ [1, +∞],...
