  1. July 16, 2019Algebraic Combinatorics Seminar - Stephen Melczer

    Title: From Combinatorics to Computer Algebra and Morse Theory - Making Sense of Multivariate Asymptotics

    Speaker: Stephen Melczer
    Affiliation: University of Pennsylvania
    Room: MC 5479

    Abstract:

    The  asymptotic study  of  multivariate  generating  functions comprises  the  domain  of  Analytic Combinatorics  in Several Variables (ACSV).

  2. July 18, 2019Algebraic Combinatorics Seminar - Lucia Rotheray

    Title: Incidence bialgebras of monoidal categories

    Speaker: Lucia Rotheray
    Affiliation: Technische Universität Dresden
    Room: MC 5417

    Abstract:

    We begin with Joni and Rota's definition of the incidence coalgebra of a category or partially ordered set and then discuss some cases where a monoidal product on a category turns this coalgebra into a bialgebra.

  3. July 19, 2019Combinatorial Optimization Reading Group - Sharat Ibrahimpur

    Title: Stable Flows

    Speaker: Sharat Ibrahimpur
    Affiliation: University of Waterloo
    Room: MC 5479

    Abstract:

    We describe a flow model that generalizes ordinary network flows the same way as stable matchings generalize the bipartite matching problem.
