    Title: A single pass bijection between certain quarter plane lattice walks and certain Motzkin-like paths.

    Speaker: Nick Olson-Harris
    Affiliation: University of Waterloo
    Room: MC 6486

    Abstract: A p-tandem quarter plane walk is a walk starting at the origin and remaining in the first quadrant using the steps (1,-1) and (-n, p-n) for n between 0 and p.

    Title: The c2 invariant at p=2 by counting edge bipartitions

    Speaker: Karen Yeats
    Affiliation: University of Waterloo
    Room: MC 5501
