Bounds on … WebbThus, the inequality (1) takes the form of a Sobolev inequality for fractional derivatives Cn(g, √ −∆g) ≥ kgk2 L 2(n−1) n−2 (Rn−1, (7) for which Lieb’s sharp HLS inequality ([5]) yields the sharp constant, including all the cases of equality. Another important approach to Escobar’s inequality is based on transportation theory [7].
