Explore the intriguing world of topological data analysis in this 39-minute conference talk from the Applied Algebraic Topology Network. Delve into the curious behavior of "topological noise" exhibited by the circle, challenging conventional wisdom in the field. Discover how random Cech complexes constructed from the circle can be homotopy equivalent to bouquets of n-spheres with positive probabilities. Learn about intervals of filtration radii where higher Betti numbers become arbitrarily large, providing new insights into the complex relationship between simplicial complexes and manifold topology.
