*********************************** * Princeton Discrete Math Seminar * *********************************** Speaker: Micha Christoph, ETH Zurich Thursday 10th September, 3:00 in Fine Hall 224. Title: Robustness and hyperstability for the Erdos-Gallai theorem The Erdos-Gallai theorem states that every graph of average degree d contains a cycle of length at least d. Alp Muyesser, Yuval Wigderson and I recently proved a robust and a hyperstability version of this theorem. At the core of the argument lies a very general structure theorem about graphs that originates from results of Pokrovskiy concerning the hyperstability of bounded-degree trees. In this talk, I will focus on explaining and motivating this structure theorem as well as providing some intuition on how to apply it. ---------------------------------- Anyone wishing to be added to or removed from the mailing list should contact Paul Seymour (pds@math.princeton.edu)
