#### Optimal parameters for consequences **of** tangential and two-frequency decompositions

A preconditioner for large **systems** **of** **linear** **equations** based on an incomplete block-decomposition for a block-tridiagonal matrices is considered. This method generalizes methods are developed by Buzdin and Wittum [1; 2]. A method **of** choosing quasioptimal parameters for consequences **of** tangential ...

#### Development **of** Parallel Algorithms for Solving **Systems** **of** **Linear** Algebraic **Equations**

For solving **systems** **of** **linear** **equations** with dense **system** matrix there is presenting a parallel algorithm **of** SOR-method. There is showing OpenMP-programm for the parallel algorithm. There are giving the results **of** numerical experiments.
