Splitting schemes are attributed to the transition from a complex problem to a chain of simpler problems. This book shows how to construct additive difference schemes (splitting schemes) to solve approximately unsteady multi-dimensional problems for PDEs. Two classes of schemes are highlighted: methods of splitting with respect to spatial variables (alternating direction methods) and schemes of splitting into physical processes. Also regionally additive schemes (domain decomposition methods) and unconditionally stable additive schemes of multi-component splitting are considered for evolutionary equations of first and second order as well as for systems of equations. The book is written for specialists in computational mathematics and mathematical modeling. All topics are presented in a clear and accessible manner.Initial value problemsBoundary value problemsDifferential operatorsMathematical modelsIterative Methods.Operator Splitting.Regularized Additive Schemes.Summarized Approximation.Transition Operator Approximations.Two-Component Splitting.Vector Additive Schemes.Initial value problems.Boundary value problems.Differential operators.Mathematical models.515/.724SK 920rvkVabishchevich P.
