On the Topology of the Cambrian Semilattices [PDF]
Discrete Mathematics & Theoretical Computer Science, 2013 For an arbitrary Coxeter group $W$, David Speyer and Nathan Reading defined Cambrian semilattices $C_{\gamma}$ as certain sub-semilattices of the weak order on $W$.

Structural Properties of the Cambrian Semilattices -- Consequences of Semidistributivity
, 2013 The $γ$-Cambrian semilattices $\mathcal{C}_γ$ defined by Reading and Speyer are a family of meet-semilattices associated with a Coxeter group $W$ and a Coxeter element $γ\in W$, and they are lattices if and only if $W$ is finite. In the case where $W$ is the symmetric group $\mathfrak{S}_{n}$ and $γ$ is the long cycle $(1\;2\;\ldots\;n)$ the ...
