| Apr 19 at 4:46 | comment | added | AGenevois | Indeed, Haglund and Wise's result is something I have in mind. I think it should be possible to embed $C(\Gamma)$ into a new Coxeter group $C(\Gamma')$ as a standard parabolic subgroup in such a way that the double coset $\langle \Phi \rangle \langle \Psi \rangle$ coincides, up to finite index, with a $\mathrm{Cross}(A,B)$ for some walls $A,B$. | |
