ON SOLVABILITY CONDITIONS FOR ELLIPTIC PSEUDO-DIFFERENTIAL EQUATIONS IN A CERTAIN MULTIDIMENSIONAL CONE
摘要
Starting from a special factorization for an elliptic symbol of a pseudo-differential operator, we find the unique solution from a certain Sobolev-Slobodetskii space to the corresponding equation. To obtain a solution from the prescribed Sobolev-Slobodetskii space, one needs solvability conditions. The paper describes such solvability conditions for certain situations.
