Optimal parameters for consequences of tangential and two-frequency decompositions
... 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 and two-frequencies decompositions based on analysis of model problems is developed. It’s convergence rate is better than ADI’s convergence rate in commutational case..

Tangential decomposition and its generalization
We present a preconditioner for large systems of linear equations based on the incomplete block decomposition for block-tridiagonal matrices. This method generalizes frequency-filtering method of G. Wittum [1] and methods developed in [2–4] etc.

Optimal parameters and sharp estimates of the convergence rate of the tangent expansion
In this paper we conceder the properties of the tangential incomplete block LU — decomposition. We present an analytical approach for determination of the optimal values of the decomposition parameter and derive sharp estimates of the convergence rate for a broad class of model problems. Numerical results prove that high convergence ...
