Title: Generalized quadrangles VI: flocksSpeaker: Krystal Guo Affiliation University of Waterloo Roo: MC 6486
Abstract: We will look at linear and non-linear flocks. We will give constructions of generalized quadrangles arising from flocks of cones in $PG(3,q)$. Please note that the seminar starts at 3 pm.
Title: The Tutte polynomial and its extensionsSpeaker: Iain Moffatt Affiliation: University of London Room: MC 5417 CHANGED TO MC 6486
Abstract: The Tutte polynomial is one of the most important and most studied graph polynomials. It is important not only because it encodes a large amount of combinatorial information about a graph, but also because of its applications to areas such as statistical physics and knot theory.
