  • Atlantic Graph Theory Seminar

    Online via Zoom

    Speaker #1: Peter Collier, Dalhousie University Title #1: Zero Forcing on Twisted Hypercubes Abstract #1: The hypercube stands out as a compelling and versatile structure that extends the geometric notion of a cube into higher dimensions. We study the twisted hypercube

    A tangent category approach to operadic geometry Marcello Lanfranchi December 19, 2024 @ 1:30pm Abstract: A tangent category consists of a collection of abstract objects equipped with a structure, called a tangent structure, which makes those abstract objects into locally linear geometric spaces. In my

  • Combinatorial Algebra meets Algebraic Combinatorics 22nd annual workshop

    York University 4700 Keele Street, Toronto, Ontario, Canada

    The Combinatorial Algebra meets Algebraic Combinatorics (CAAC) workshop is an annual meeting taking place in Canada since 2004, with a focus on the continuously evolving interactions between combinatorial algebra and algebraic combinatorics. These meetings provide a strong connection between the
