Abstract: | Summary Least constantsc for the well-known Sobolev inequality fcfm, G,fHm(G) are obtained in closed form by a reproducing kernel technique, where the Sobolev spaceHm(G) for a domainG in n is defined as the completion ofCm(G) with respect to the Sobolev norm given by, where is the norm ofL2(G) and is the supremum norm onG. Numerical values for the case whereG is the n are given. |
