Sharp constant in a sobolev trace inequality

WebbThe sharp trace inequality of José Escobar is extended to traces for the fractional Laplacian on R n, and a complete characterization of cases of equality is discussed. The proof proceeds via Fourier transform and uses Lieb’s sharp form of the Hardy-Littlewood-Sobolev inequality. References Similar Articles Additional Information 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. The constant in the Michael-Simon Sobolev inequality depends only on the dimension; however, the constant is not sharp.
