Iterative methods for solving saddle problems

For the first time in one book, all known iterative methods for large systems of linear algebraic block structure equations are considered, which have a saddle point as a solution: the ideas of constructing, conditions of convergence and optimization issues are analyzed in detail. The results of the analysis are presented in the form of a convenient formula. The existing application is focused on the use of the theory for numerical modeling in hydrodynamics and related areas.
For scientists in the field of computational mathematics, graduate students and students, as well as for engineers and researchers in applied areas.
The publication was implemented with the financial support of the Russian Foundation for Fundamental Research on Project No. 09-01-07025
