Simon Lentner, Daniel Nett

Given a finite set of roots of unity, we show that all power sums are non-negative integers iff the set forms a group under multiplication. The main argument is purely combinatoria…

New -matrices for small quantum groups

Simon Lentner, Daniel Nett

In this article we construct a large family of -matrices for various extensions of small quantum groups by grouplike elements. The extensions are in correspondence to lattices b…
