Friezes satisfying higher SL-determinants
Karin Baur, Eleonore Faber, Sira Gratz +2
In this article, we construct SL-friezes using Plücker coordinates, making use of the cluster structure on the homogeneous coordinate ring of the Grassmannian of -spaces in…

Conway-Coxeter friezes and mutation: a survey
Karin Baur, Eleonore Faber, Sira Gratz +2
In this survey article we explain the intricate links between Conway-Coxeter friezes and cluster combinatorics. More precisely, we provide a formula, relying solely on the shape of…

Homotopy invariants of singularity categories
Sira Gratz, Greg Stevenson
We present a method for computing -homotopy invariants of singularity categories of rings admitting suitable gradings. Using this we describe any such invariant, e.g.…
