Transfinite mutations in the completed infinity-gon
Karin Baur, Sira Gratz
We introduce mutation along infinite admissible sequences for infinitely marked surfaces, that is surfaces with infinitely many marked points on the boundary. We show that mutation…

Strongness of companion bases for cluster-tilted algebras of finite type
Karin Baur, Alireza Nasr-Isfahani
For every cluster-tilted algebra of simply-laced Dynkin type we provide a companion basis which is strong, i.e. gives the set of dimension vectors of the finitely generated indecom…

Extensions between Cohen-Macaulay modules of Grassmannian cluster categories
Karin Baur, Dusko Bogdanic
In this paper we study extensions between Cohen-Macaulay modules for algebras arising in the categorifications of Grassmannian cluster algebras. We prove that rank 1 modules are pe…
