This allows us to formalize and study a framework of "cyclic reducibility" in Coxeter theory, and apply it to model conjugacy.

Usually, one says that graph products interpolate between free products (when Γ has no edge) and direct sums (when Γ is a complete graph).

We say that w ∈ W is cyclically fully commutative (CFC) if every cyclic shift of every reduced expression for w is fully … WebLet W be a Coxeter group. We define an element w ∈ W to be fully commutative if any reduced expression for w can be obtained from any other by means of braid relations that only involve commuting generators. We give several combinatorial characterizations of this property, classify the Coxeter groups with finitely many fully commutative elements, …
