The stability space of a module is the cone of vectors which make the module semistable. These cones are defined in terms of inequalities; in this paper we draw insights from consi…

Osamu Iyama, Nicholas J. Williams

We show that indecomposable two-term presilting complexes over $Π_{n}$ , the preprojective algebra of $A_{n}$ , are in bijection with internal $n$ -simplices in the prism $Δ_{n} \time…
