A geometric perspective on the $τ$ -cluster morphism category

Sibylle Schroll, Aran Tattar, Hipolito Treffinger +1

We show how the $τ$ -cluster morphism category may be defined in terms of the wall-and-chamber structure of an algebra. This geometric perspective leads to a simplified proof that t…

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…
