Existence of symmetric maximal noncrossing collections of $k$ -element sets

Andrea Pasquali, Erik Thörnblad, Jakob Zimmermann

We investigate the existence of maximal collections of mutually noncrossing $k$ -element subsets of ${1, \dots, n}$ that are invariant under adding $k (mod n)$ to all…

Extreme representations of semirings

Chih-Whi Chen, Brendan Frisk Dubsky, Helena Jonsson +4

This is a write-up of the discussions during the meetings of the study group on representation theory of semirings which was organized at the Department of Mathematics, Uppsala Uni…

Simple transitive $2$ -representations of left cell $2$ -subcategories of projective functors for star algebras

Jakob Zimmermann

In this paper we study simple transitive $2$ -representations of certain $2$ -subcategories of the $2$ -category of projective functors over a star algebra. We show that in the simple…

Simple transitive $2$ -representations of some $2$ -categories of projective functors

Jakob Zimmermann

We show that every simple transitive $2$ -representation of the $2$ -category of projective functors for a certain quotient of the quadratic dual of the preprojective algebra associa…
