Webis known as Kreiss Matrix Theorem [Kr]. According to Tadmor, it has been shown originally by Kreiss (1962) with the inequality P(T) ≤ Cste(ρ(T))nn. It is useful in proofs of stability theorems for finite difference approximations to partial differential equations. Until 1991, the inequality of Kreiss has been improved successively by Morton, WebThe first theorem gives a stability estimate which implies that errors in the numerical process cannot grow faster than linearly with s or n. It improves previous results in the literature where various restrictions were imposed on S and ~o(z), including ~J(z) ~= 0 for z E OS and S be bounded.
