Hubungan di antara jejari spektrum dan faktor pengenduran berlebihan untuk masalah nilai sempadan berkala dalam persamaan pembeza separa eliptik

Abstract

The discretization of the second-order linear self-adjoint ellliptic partial differential equation problem subject to periodic boundary conditions results in a system of linear equations of the form Mu = s, where M is a block cyclic tridiagonal square matric. In this paper, the relationship between the spectral radius and overrelaxation factor for the problem is derived.
