Title: Persistent homology of function spaces
Speaker: Fedor Manin - University of Toronto (Host): Rafal Komendarczyk
Abstract: Suppose you're given two homotopic maps between spaces. Does a homotopy between them have to pass through much more geometrically complicated maps? More generally, if you have a homologically trivial cycle in a function space, is it possible to trivialize it in the subspace of maps that are not too complicated? This can be thought of as studying the "Morse landscape" of a height function on the mapping space. In joint work with Jonathan Block and Shmuel Weinberger, we make this precise using the language of persistent homology and give some first results.
