The saturation conjecture for nondegenerate Jacobi-finite QPs

Let (Q,S)(Q,\mathcal{S}) be a nondegenerate Jacobi-finite quiver with potential. A pair (δ,ϵˇ)(\delta,\check\epsilon) has the saturation property when hom(δ,ϵˇ)=0\operatorname{hom}(\delta,\check\epsilon)=0 whenever hom(mδ,nϵˇ)=0\operatorname{hom}(m\delta,n\check\epsilon)=0 for some m,nNm,n\in\mathbb{N}. A QP is saturated when this property holds for every such pair. Saturation conjecture. Every nondegenerate Jacobi-finite QP is saturated. This generalizes the ordinary saturation property for acyclic quivers and, by the proposition immediately preceding the statement, is equivalent to the hom-fluent property and to the generic pairing equality for each pair. The supplied status is unknown.
