A Crossing Lemma for Annular Regions and Invariant Sets with an Application to Planar Dynamical Systems
We present a topological result, named crossing lemma, dealing with the existence of a continuum which crosses a topological space between a pair of “opposite” sides. This topological lemma allows us to obtain some fixed point results. In the works of Pascoletti et al., 2008, and Pascoletti and Zano...
