Russ. Acad. Sci., Dokl., Math. 49, No. 3, 564-567 (1994); translation from Dokl. Akad. Nauk, Ross. Akad. Nauk 336, No. 5, 590-591 (1994).
By the method of a priori estimates the author proves the unique solvability of certain problems for the wave equation. The Dirichlet problem is one of them. The existence theorem and a priori estimate are proved in the Sobolev space \(W_2^1\) with a weight.
