Abstract
Let be a compact metric space with no isolated points, and a homeomorphism. Consider a sequence of shrinking open balls with centers and radii . For every point and , consider which ball the trajectory of the point first visits. We find that whenever the closure of is nowhere dense, and with very minor restrictions on , the typical trajectory will first visit, for each , the ball , for infinitely many . This is never the case, should be somewhere dense. Keywords: Open Dynamical System, Topological Dynamics, Transitive Homeomorphism, Baire category. MSC2020: 37B05, 37B20, 18F60, 54E52.
