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…

Counting Quasi-Idempotent Irreducible Integral Matrices

Erik Thörnblad, Jakob Zimmermann

Given any polynomial $p$ in $C [X]$ , we show that the set of irreducible matrices satisfying $p (A) = 0$ is finite. In the specific case $p (X) = X^{2} - n X$ , we count the number of irreducib…
