Positive Solutions of Some Three-point Boundary Value Problems via Fixed Point Index for Weakly Inward A-proper Maps
in which the second derivative may occur nonlinearly. Positive solutions for the case f (t,u,u′,u′′) = g(t)h(u) have been studied by Ma [15] and Webb [20, 21], when f (t,u,u′,u′′) = h(t,u) by He and Ge [5] and also by Lan [11]. The case f (t,u,u′,u′′) = g(t)h(u,u′) has been studied by Feng [4]. The results in [4, 15] are obtained by means of Krasnosel’skiı̆’s theorem [8], the ones in [5] use Leg...

متن کاملA Fixed-point Theorem for Inward and Outward Maps
The Schauder-Tychonoff theorem states that a continuous function from a compact convex subset of a locally convex topological vector space into itself must have a fixed point ([1, Chapter V, 10.5], or [2]). Using this theorem, we obtain here a stronger result, stating that a map from such a set into the surrounding vector space has a fixed point if the directions in which the points are moved s...

متن کاملVector ultrametric spaces and a fixed point theorem for correspondences
In this paper, vector ultrametric spaces are introduced and a fixed point theorem is given for correspondences. Our main result generalizes a known theorem in ordinary ultrametric spaces.
