The higher Stasheff--Tamari orders in representation theory

Nicholas J. Williams

We show that the relationship discovered by Oppermann and Thomas between triangulations of cyclic polytopes and the higher Auslander algebras of type $A$ , denoted $A_{n}^{d}$ , is a…

Stability spaces of string and band modules

Sibylle Schroll, Aran Tattar, Hipolito Treffinger +2

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…

Triangulations of prisms and preprojective algebras of type $A$

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…
