Abstract

This paper studies mixed finite element approximations to the solution of the viscoelasticity wave equation. Two new transformations are introduced and a corresponding system of first‐order differential‐integral equations is derived. The semi‐discrete and full‐discrete mixed finite element methods are then proposed for the problem based on the Raviart–Thomas–Nedelec spaces. The optimal error estimates in L^2^‐norm are obtained for the semi‐discrete and full‐discrete mixed approximations of the general viscoelasticity wave equation.

## Abstract A null space algorithm is considered to solve the augmented system produced by the mixed finite‐element approximation of Darcy's Law. The method is based on the combination of an orthogonal factorization technique for sparse matrices with an iterative Krylov solver. The computational ef
