Atlantic Graph Theory Seminar
Speaker: Shahriyar Pourakbar Saffar, Memorial University of Newfoundland Title: Existence of uniquely 2-colourable 4-cycle decompositions: A constructive proof Abstract: A cycle system of order $n$ is a decomposition of the edges of the complete graph $K_n$ into cycles of a fixed length. A cycle system is said to be $k$-colourable if we can assign $k$ colours to its vertices so that no cycle is monochromatic. If a cycle system is $k$-colourable but not $(k-1)$-colourable, it is called $k$-chromatic. A $k$-colourable…

Atlantic Graph Theory Seminar: Jorik Jooken – Feb 4
Speaker: Jorik Jooken, KU Leuven Kulak Title: On vertex-girth-regular graphs: (Non-)existence, bounds and enumeration Abstract: A vertex-girth-regular vgr(v,k,g,lambda)-graph is a k-regular graph of girth g and order v in which every vertex belongs to exactly lambda cycles of length g. While all vertex-transitive graphs are necessarily vertex-girth-regular, the majority of vertex-girth-regular graphs are not vertex-transitive. Similarly, while many of the smallest k-regular graphs of girth g, the so-called (k,g)-cages, are vertex-girth-regular, infinitely many vertex-girth-regular graphs of degree k and girth…

Date and Time: Wednesday, February 11, 3.40 pm Atlantic time Speaker: JD Nir, Oakland University Title: The Second Common Neighbourhood Conjecture Abstract: The Second Common Neighbourhood Conjecture is a question about the structure of shared neighbours in a graph. At first glance, it seems like a nice problem for a new researcher to study: it requires only a basic understanding of graph theory to state, examples are easy to understand, and one can quickly prove the conjecture holds in certain…

Date and Time: Wednesday, February 25, 3.40 pm Atlantic time Speaker: Erin Meger, Queens University Title: Decomposing Forbidden Minors for Pursuit-Evasion Abstract: In this talk, we consider the pursuit-evasion game Cops and Robbers. The game is played on a graph between two players: a set of cops and a single robber, who take turns moving along the edges. The cop number of a graph is the minimum number of cops needed to guarantee capture of the robber, meaning they eventually…

Atlantic Graph Theory Seminar
Speaker: Andrea Burgess, University of New Brunswick Title: Colourings of combinatorial designs Abstract: A combinatorial design is a pair $(V,\mathcal{B})$ where $V$ is a nonempty set of points, and $\mathcal{B}$ is a collection of subsets of $\mathcal{B}$, called blocks. A $c$-colouring of a design $(V,\mathcal{B})$ is a function $f:V \rightarrow C$, where $C$ is a set of $c$ colours, such that each block contains at least two points of different colours. The design's chromatic number is the least value of…

21st CMS-UPEI-AARMS Regional Math Camp
For more than 20 years, the School of Mathematical and Computational Sciences (SMCS), UPEI has hosted a Math Camp for students in grades 10 and 11 from PEI high schools. The Math Camp is the SMCS’s primary outreach effort. Its goals are to give some of PEI’s best students an opportunity to broaden their mathematical horizons beyond what they see in their course work, and to encourage them to continue their math studies at university. It is held for a…
