Title
The inexact Euler-extrapolated block preconditioners for a class of complex linear systems
Abstract
By utilizing Euler-extrapolated technique, we construct several inexact block preconditioners for solving a broad class of complex linear systems. The spectral properties of the preconditioned matrices are studied. Moreover, we determine the quasi-optimal parameter of these preconditioners. Numerical results are given to verify the effectiveness of the proposed inexact preconditioners.
