Mengxue Yang (UIC): Combinatorics of Coxeter systems

We continue to learn about Coxeter groups following Anne Thomas' "Geometric and topological aspects of Coxeter groups and buildings". There are nice combinatorial properties associated to a Coxeter system. For example, the Cayley graph of a Coxeter system must have nice symmetries and is thus a reflection system. We will visualize everything with $D_6$.
