Linear-ordering conjecture for reflection representations of skew-symmetrizable matrices

Let BB be a skew-symmetrizable matrix indexed by I=1,,n\mathcal I={1,\ldots,n}. For a mutation sequence w\boldsymbol{w}, let riwr_i^{\boldsymbol{w}} be the associated reflections, let CwC^{\boldsymbol{w}} be its CC-matrix, and let pipi be the representation determined by a linear ordering precprec and its associated generalized intersection matrix. Linear-ordering conjecture. For any skew-symmetrizable matrix BB, there exists a linear ordering precprec on I\mathcal I such that, if boldsymbolwboldsymbol{w} and boldsymbolvboldsymbol{v} are mutation sequences satisfying

Cboldsymbolw=Cboldsymbolv,C^{boldsymbol{w}}=C^{boldsymbol{v}},

then

pi(riboldsymbolw)=pi(riboldsymbolv),i=1,,n.pi(r_i^{boldsymbol{w}})=pi(r_i^{boldsymbol{v}}),\qquad i=1,\ldots,n.

In particular, Bboldsymbolw=BboldsymbolvB^{boldsymbol{w}}=B^{boldsymbol{v}}. The conjecture asks whether one ordering makes the represented reflections depend only on the resulting CC-matrix; the paper investigates this problem in the setting of quiver mutations, while its general status is not resolved in the supplied text.
