Simplicial arrangements on convex cones
Michael Cuntz, Bernhard Mühlherr, Christian J. Weigel
We introduce the notion of a Tits arrangement on a convex open cone as a special case of (infinite) simplicial arrangements. Such an object carries a simplicial structure similar t…

On wild frieze patterns
Michael Cuntz
In this note, among other things, we show: There are periodic wild SLk-frieze patterns whose entries are positive integers. There are non-periodic SLk-frieze patterns whose entries…

A simplicial complex of Nichols algebras
Michael Cuntz, Simon Lentner
We translate the concept of restriction of an arrangement in terms of Hopf algebras. In consequence, every Nichols algebra gives rise to a simplicial complex decorated by Nichols a…
