Theorem on well-posedness of the difference scheme in the difference analogue of Holder spaces with a weight is established. In applications, coercive stability estimates for the solutions of difference schemes of nonlocal boundary value problems for elliptic problems are obtained.eninfo:eu-repo/semantics/closedAccessDifference schemeelliptic equationnonlocal boundary value problemwell-posednessArticle38101244125910.1080/01630563.2017.1316994Q3WOS:0004115195000052-s2.0-85019729341Q2
