Abstract:
In 2015, Chris Godsil and Karen Meagher proposed [GM15] systematical studies of EKR properties of strongly regular graphs.
In particular, they emphasized two infinite families of strongly regular graphs: block graphs pf orthogonal arrays and block graphs of 2-designs, and posed several interesting open problems. Recently, together with my colleagues Chi Hoi Yip and Elena Konstantinova, we made a progress (in [GY23] and [GK23], respectively) towards some of the problems.
In my talk, we will discuss the background on the EKR properties of strongly regular graphs and our recent results.
