RT Journal Article T1 The best Sobolev trace constant as limit of the usual Sobolev constant for small strips near the boundary A1 Arrieta Algarra, José María A1 Rodríguez Bernal, Aníbal A1 Rossi, Julio D. AB In this paper we prove that the best constant in the Sobolev trace embedding H1() ,! Lq(@) in a bounded smooth domain can be obtained as the limit as " ! 0 of the best constant of the usual Sobolev embedding H1() ,! Lq(!", dx/") where !" = {x 2 : dist(x, @) < "} is a small neighborhood of the boundary. We also analyze symmetry properties of extremals of this last embedding when is a ball.
