Second, we get existence results when the lower and upper solutions are not well-ordered. Finally, we present mu

Die Bevölkerung in Ost- und Westdeutschland Our results will rely on our generalization of Krasnosel’skiı̆’s fixed point theorem and its multidimensional version for multivalued maps, respectively. We also obtain multiplicity results for a kind of three point boundary value problem via our extension of Leggett–Williams’ fixed point theorem.
