ABSTRACT
An iterative predictor-corrector technique for the elimination of the approximate factorization errors which result from the factorization of implicit, three-point, compact, linearized θ-methods in multidimensional reaction-diffusion equations is proposed, and its convergence and linear stability are analyzed. Compact, approximate factorization techniques which do not account for the approximate factorization errors and which involve three-point stencils for each one-dimensional operator are developed. The techniques are applied to a nonlinear, two-species, two-dimensional system of reaction-diffusion equations in order to determine the approximate factorization errors as functions of the allocation of the reaction terms, space and time.
