Abstract:

Making use of a surface integral defined without use of the partition of unity, trace theorems and the Gauss-Ostrogradskij theorem are proved in the case of three-dimensional domains Omega with a Lipschitz-continuous boundary for functions belonging to the Sobolev spaces H1,p(Omega) (1 le p < infin). The paper is a generalization of the previous author's paper which is devoted to the line integral.
