Root Systems In Finite Symplectic Vector Spaces
Simon D. Lentner
We study subsets in possibly degenerate symplectic vector spaces over finite fields, which are stable under a given Coxeter/Weyl reflection group. These symplectic root systems pro…

New Large-Rank Nichols Algebras Over Nonabelian Groups With Commutator Subgroup Z_2
Simon D. Lentner
In this article, we explicitly construct new finite-dimensional, link-indecomposable Nichols algebras with Dynkin diagrams of type An,Cn,Dn,E6,E7,E8,F4 over any group G with commut…
