Equivalent Solutions of Nonlinear Equations in a Topological Vector Space with a Wedge

Journal of Inequalities and Applications volume 2007, Article number: 046041 (2007) Cite this article

Abstract

We obtain efficient conditions under which some or all solutions of a nonlinear equation in a topological vector space preordered by a closed wedge are comparable with respect to the corresponding preordering. Conditions sufficient for the equivalence of comparable solutions are also given. The wedge under consideration is not assumed to be a cone, nor any continuity conditions are imposed on the mappings considered.
