  1. Jan. 23, 2020Algebraic Combinatorics Seminar - Karen Yeats

    Title: Some places matroids appear in quantum field theory and some places I would like them to

    Speaker: Karen Yeats
    Affiliation: University of Waterloo
    Room: MC 5417

    Abstract:

    I will discuss some places matroids have appeared in my work in quantum field theory, including some older work on numerator structure with Dirk Kreimer and some work in progress with Iain Crump on period identities.

  2. Jan. 23, 2020Graphs and Matroids Seminar - Jane Gao

    Title: Uniformly generate graphs with given degrees rapidly

    Speaker: Jane Gao
    Affiliation: University of Waterloo
    Room: MC 5479

    Abstract:

    I will survey the research on exact/approximate uniform generation of graphs with prescribed degrees.

  3. Jan. 24, 2020Combinatorial Optimization Reading Group - Ben Moore

    Title: On the Strong Nine Dragon Tree Conjecture

    Speaker: Ben Moore
    Affiliation: University of Waterloo
    Room: MC 5417

    Abstract:

    Nash-Williams forest covering theorem says that a graph decomposes into $k$ forests if and only if it has fractional arboricity at most $k$. In 2012 Mickeal Montassier, Patrice Ossona de Mendez, Andre Raspaud, and Xuding Zhu  proposed a significant strengthening of Nash-Williams Theorem, called the Strong Nine Dragon Tree Conjecture.
