SUMMARY:Atlantic Graph Theory Seminar
DESCRIPTION:Colourings of Balanced Incomplete Block Designs That Are Almost Locally Equitable \nDate and Time: Wednesday\, January 14\, 3.40 pm Atlantic time\nSpeaker: William Kellough\, Memorial University of Newfoundland \nAbstract: In this talk\, we study $\ell$-colourings of $(v\,k\,\lambda)$-BIBDs where within each block\, one colour is absent and the rest appear exactly $\frac{k}{\ell-1}$ times. We give necessary conditions for such colourings to exist. We show how Hadamard matrices\, affine planes\, and twin prime powers can be used to construct such coloured BIBDs. \nZoom link:\nhttps://us02web.zoom.us/j/88013261876?pwd=XGocyHqvseXY8metPztPoSuulEEejX.1 \nMeeting ID: 880 1326 1876\nPasscode: 357963
