The solvable degree of a Schur algebra
Gabriele Nebe, David Schlang
The solvable degree of a Schur algebra is the greatest common divisor of all integers such that is a direct summand of the rational group algebra $\Q G$ for…
The second minimum of Barnes-Wall lattices
Gabriele Nebe
The paper gives a recursive construction of the Barnes-Wall lattices as subdirect products. This is used to show that the Barnes-Wall lattices of minimum do not contain any vec…
Unitary discriminants of characters
Gabriele Nebe
Together with David Schlang we computed the discriminants of the invariant Hermitian forms for all indicator even degree absolutely irreducible characters of the ATLAS groups s…
Subspaces Fixed by a Nilpotent Matrix
Marvin Anas Hahn, Gabriele Nebe, Mima Stanojkovski +1
The linear spaces that are fixed by a given nilpotent matrix form a subvariety of the Grassmannian. We classify these varieties for small . Mutiah, Weekes and Yacob…
On orthogonal discriminants of characters
Gabriele Nebe
An ordinary character of a finite group is called orthogonally stable, if all non-degenerate invariant quadratic forms on any module affording the character have the same d…
Orthogonal Stability
Gabriele Nebe, Richard Parker
A character (ordinary or modular) is called orthogonally stable if all non-degenerate quadratic forms fixed by representations with those constituents have the same determinant mod…
