The stability estimates for the solutions of these difference schemes are established. In practice, one-dimensional hyperbolic equation with nonlocal boundary conditions and multidimensional hyperbolic equation with Dirichlet conditions are considered. The stability estimates for the solutions of difference schemes for the nonlocal boundary value hyperbolic problems are obtained and the numerical results are presented to support our theoretical statements.eninfo:eu-repo/semantics/closedAccessMathematicsHyperbolic equationNonlocal boundary value problemsStabilityBoundary-value-problemsParabolic equationsSecond order of accuracy stable difference schemes for hyperbolic problems subject to nonlocal conditions with self-adjoint operatorProceedings Paper0003022398001472-s2.0-818552031915976001389MathematicsAppliedDifference Scheme; Nonlocal Boundary Value Problems; Third Order Differential Equation
