Fixed points of decreasing operators in ordered Banach spaces and applications to nonlinear second order elliptic equations. (English) Zbl 1191.47075
Summary: We consider some decreasing operators in ordered Banach spaces. We study the existence and uniqueness of fixed points and properties of the iterative sequences for these operators. Lastly, the results are applied to nonlinear second order elliptic equations.
