Explore a 52-minute lecture by Alexander Lytchak from the Hausdorff Center for Mathematics that delves into the concept of submetries - maps between metric spaces that send balls onto balls of the same radii. Learn how these mathematical structures generalize Riemannian submersions and quotient maps for isometric group actions. Discover the topological, analytic, and algebraic structural results for submetries as Lytchak presents a comprehensive examination of this important mathematical concept.
