Paperback. Condizione: New. Print on Demand. This book introduces the theory and application of two closely related families of iterative methods for solving elliptic finite element problems. Both methods have proven to be well-suited for parallel computing on many processors, especially for systems with strong grading of the mesh. For the first method, called the multiplicative Schwarz method, the author establishes optimal convergence rates independent of the number of subregions and the mesh size. The second method, called the additive Schwarz method, is shown to have the same property for a specific variant, and a convergence proof is given for a more general variant. The author also discusses optimal iterative refinement methods, which are closely related to the Schwarz methods. These methods can be used to improve the accuracy of finite element solutions by locally refining the mesh. The author provides a detailed analysis of these methods and establishes their optimal convergence rates. This book is a valuable resource for researchers and practitioners working in the fields of numerical analysis, scientific computing, and computational engineering.
