Abstract
Recently, Goldberg studied in [M. Goldberg, SIAM J. Numer. Anal., 35 (1998), pp. 478-493, M. Goldberg, SIAM J. Numer. Anal., 35 (1998), pp. 1995-2003] stability conditions of a well-known family of difference schemes for the following multidimensional parabolic system of second order:
∂u(x, t)/∂t = ∑1≤p≤q≤s Apq ∂2u(x, t)/∂xp∂xq + ∑1≤p≤s Bp ∂u(x, t)/∂xp + Cu(x, t).
Here we present a modified stability condition for the above problem, and prove that this condition is optimal in some sense.
