A geometric perspective on the -cluster morphism category
Sibylle Schroll, Aran Tattar, Hipolito Treffinger +1
We show how the -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
Osamu Iyama, Nicholas J. Williams
We show that indecomposable two-term presilting complexes over , the preprojective algebra of , are in bijection with internal -simplices in the prism $Δ_{n} \time…
Efficient and flexible causal mediation with time-varying mediators, treatments, and confounders
Iván Díaz, Nicholas Williams, Kara E. Rudolph
Interventional effects have been proposed as a solution to the unidentifiability of natural (in)direct effects under mediator-outcome confounders affected by the exposure. Such con…
Causal mediation with instrumental variables
Kara E. Rudolph, Nicholas Williams, Ivan Diaz
Mediation analysis is a strategy for understanding the mechanisms by which treatments or interventions affect later outcomes. Mediation analysis is frequently applied in randomized…
Quiver combinatorics for higher-dimensional triangulations
Nicholas J. Williams
We investigate the combinatorics of quivers that arise from triangulations of even-dimensional cyclic polytopes. Work of Oppermann and Thomas pinpoints such quivers as the prototyp…
