Abstract
In a recent series of papers, Goldberg [G1, G2] and Sun and Yuan [SY] studied the L 2-stability of a well-known family of finite difference approximations for the initial-value problem associated with the multispace-dimensional parabolic system
where A pq ,B p and C are constant matrices, A pq being Hermitian. In the present paper we discuss these earlier results and complete the underlying theory by answering four open questions.
