Discrete Operators in Canonical Domains
Vladimir Borisovich Vasilyev · Open Access Repository (Belgorod State National Research University) · 2017
In this paper, we consider a certain class of discrete pseudo-differential operators in a sharp convex cone and describe their invertibility conditions in L₂-spaces. For this purpose we introduce a concept of periodic wave factorization for elliptic symbol and show its applicability for the studying
