The authors provide a systematic presentation of the recent advances in robust algebraic multilevel methods and algorithms, e.g., the preconditioned conjugate gradient method, algebraic multilevel iteration (AMLI) preconditioners, the classical algebraic multigrid (AMG) method and its recent modifications, namely AMG using element interpolation (AMGe) and AMG based on smoothed aggregation. The first six chapters can serve as a short introductory course on the theory of AMLI methods and algorithms. The next part of the monograph is devoted to more advanced topics, including the description of new generation AMG methods, AMLI methods for discontinuous Galerkin systems, looking-free algorithms for coupled problems etc., ending with important practical issues of implementation and challenging applications. This second part is addressed to some more experienced students and practitioners and can be used to complete a more advanced course on robust AMLI and AMG methods and their efficient application. This book is intended for mathematicians, engineers, natural scientists etc. 410 0$aRadon series on computational and applied mathematics ;$v5. 606 $aAlgebras, Linear$xData processing 606 $aMathematical analysis 610 $aLinear Algebra. 610 $aMultigrid Method. 610 $aPartial Differential Equation. 615 0$aAlgebras, Linear$xData processing. 615 0$aMathematical analysis. 676 $a515.35 686 $aSK 540$2rvk 700 $aKraus$b Johannes$01544395 701 $aMargenov$b Svetozar$01544396 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910778468003321 996 $aRobust algebraic multilevel methods and algorithms$93798596 997 $aUNINA
