Another important approach to Escobar’s inequality is based on transportation theory [7].

Webb15 nov. 2006 · In [20], Maggi and Villani proved an optimal inequality valid on all locally Lipschitz domains : (10) where (this exponent is the critical one for the Sobolev embedding into space on the boundary), and is the isoperimetric constant. In addition, they showed that (10) is sharp on balls. This generalizes in particular a result of Brezis and Lieb ... Webba Sobolev inequality which holds on every submanifold in Euclidean space (see [1], Section 7, and [14]). This inequality is particularly useful on a minimal submanifold; in general, it contains a term involving the mean curvature.
