  • Atlantic Graph Theory Seminar

    Online via Zoom

    Detecting (Di)Graphical Regular Representations Speaker: Joy Morris, U. Lethbridge Abstract: Graphical and Digraphical Regular Representations (GRRs and DRRs) are a concrete way to visualise the regular action of a group, using (di)graphs. More precisely, a GRR or DRR on the

  • Atlantic Graph Theory Seminar

    Online via Zoom

    Speaker: Jordan Barrett, Toronto Metropolitan University Title: Graph burning, the burning number conjecture, and burning density Abstract: Graph burning is a discrete time process on a graph that acts as a simple model for the spread of social contagion in a network.

  • Atlantic Graph Theory Seminar

    Online via Zoom

    Speaker:  Leslie Hogben, Iowa State University Title:         Forts, (fractional) zero forcing, and Cartesian products of graphs Abstract: Zero forcing is an iterative process that repeatedly applies a rule to change the color of vertices of a graph $G$

  • Atlantic Graph Theory Seminar

    Online via Zoom

    Speaker: Torsten Mütze, Un. Warwick Title: Kneser graphs are Hamiltonian   Abstract: For integers k>=1 and n>=2k+1, the Kneser graph K(n,k) has as vertices all k-element subsets of an n-element ground set, and an edge between any two disjoint sets.

  • Combinatorial Algebra Meets Algebraic Combinatorics

    Montreal Montreal, Quebec, Canada

    Combinatorial Algebra Meets Algebraic Combinatorics (CAAC) is a two-day workshop bringing together researchers working at the intersection of combinatorics and algebra. It examines the role of combinatorial structures, such as permutations, matroids and polytopes, arising from problems in Schubert calculus,

  • Atlantic Graph Theory Seminar

    Online via Zoom

    Speaker: Thiago de Holleben, Dalhousie University Title: Homological invariants of graphs with no induced cycles of length divisible by 3 Abstract:  If G is a graph with large chromatic number, what can we say about its induced subgraphs? In 2014,
