The Stabd\operatorname{Stab}^d conjecture for truncated stability-condition spaces

Let (X,H)(X,H) be a smooth polarized variety over C\mathbb{C} and let d0d\geq0. Let Un>d\mathfrak U_n^{>d} be the subspace of central charges defined by the interlacing conditions and the separation bound sep((s,t))>d\operatorname{sep}(\ell(\underline s,\underline t))>d. Stabd\operatorname{Stab}^d conjecture. There exists a family of stability conditions StabH>d(X)\operatorname{Stab}_H^{*>d}(X) with respect to the HH-polarized lattice ΛH\Lambda_H such that

Forg:StabH>d(X)Hom(ΛH,C),σ=(A,Z)Z\operatorname{Forg}:\operatorname{Stab}_H^{*>d}(X)\to\operatorname{Hom}(\Lambda_H,\mathbb C),\qquad \sigma=(\mathcal A,Z)\mapsto Z

is a homeomorphism onto Un>d\mathfrak U_n^{>d}, and tensoring by OX(H)\mathcal O_X(H) preserves the family. This is one of the paper's main conjectures, refining the d=0d=0 standard-slice assertion by imposing a separation threshold; no resolution is given in the supplied text.
