Iterative and Petrov-Galerkin methods for solving a system of one- dimensional nonlinear elliptic equations. (English) Zbl 0812.65077
Summary: Two sequences of supersolutions and subsolutions are constructed. Their limits are the solutions of a system of one-dimensional nonlinear elliptic equations. A Petrov-Galerkin scheme is proposed. The existence of solutions of the resulting discrete system is proved by an iteration which also provides a numerical method.
