A fixed point theorem for convex and decreasing operators. (English) Zbl 1159.47306
Summary: We present a new fixed point theorem for noncompact, convex and decreasing operators, which extends the existing corresponding results. As a sample, we give an application of the fixed point theorem to the two-point boundary value problem for a second-order differential equation.
