Parametric extrapolation method for degenerate system of linear algebraic equations

Abstract

Abstract. In this paper we propose an extrapolation method by a spectrum shift parameter for solving degenerate system of linear algebraic equations. An estimate of the computational work for achieving the normal solution with a given accuracy as well as the advantages of the method are shown theoretically and on examples.T6m t~t.
