Abstract

In the present paper, extending Proposition 2 of [2] by the use of the techniques developed in [4], the author establishes a theorem which gives a method of a posteriori component-wise error estimation for approximate solutions to nonlinear equations. The method of error estimation based on this theorem is illustrated with a system consisting of two nonlinear equations.
