SEMINAR: Mathematics and Statistics colloquium

Graphs (also called networks) with a high degree of symmetry are particularly nice objects to study mathematically. When studying the symmetries of a graph it is often useful to look at the local symmetries, that is, those that fix a particular vertex.  An important question then becomes whether or not we can bound the number of these local symmetries. After a gentle introduction to the area, I will outline some of the results in this direction and their consequences.
