A topological characterization of the existence of fixed points and applications. Issue 2 (4th September 2013) - Khanh, Phan Quoc
Abstract We prove a topological two‐way characterization of the existence of fixed‐points, without using linear or convexity structures and provide applications in optimization‐related problems. Such a characterization is also demonstrated for a fixed‐component point, a slight generalization of a fixed point.
