Speaker: Yian Xu (University of Western Australia) Title: Constructing a 2-arc-transitive cover for a certain hypercube Time and place: 16:00 Friday 03/11/2017 in Weatherburn LT

Abstract: The canonical basis, which is a particular type of basis of a vector space will be introduced in this talk, and a sufficient and necessary condition is given to determine the existence of such a basis for a vector space. The structures of canonical bases are then used to study Cayley graphs of extraspecial $2$-groups of order $2^{2r+1}$ ($r eq 1$), which are further shown to be normal Cayley graphs and $2$-arc-transitive covers of $2r$-dimensional hypercubes. ​
