Multiparameter extrapolation and deflation methods for solving equation systems
The author studies iterative matrix extrapolation methods for solving both linear and nonlinear systems of n equations in n variables. Included as special cases are the familiar Jacobi, Gauss-Seidel and SOR methods. By permitting non-diagonal extrapolation matrices it becomes possible to study and improve deflation methods for finding several solutions of nonlinear systems.
