On the Convergence Rates of Variational Methods: III. Unsymmetric Systems
T. L. Freeman, L. M. Delves · IMA Journal of Applied Mathematics · 1974
The convergence rate theory given in previous papers (Delves & Mead (1971), Freeman, Delves & Reid (1974)) for the variational solution of the inhomogeneous equation £f = g, for Hermitian operators £, is extended to cover non-symmetric systems.
