Exterior and Symmetric Powers of Modules for Cyclic 2-Groups

Frank Himstedt, Peter Symonds

We prove a recursive formula for the exterior and symmetric powers of modules for a cyclic 2-group. This makes computation straightforward. Previously, a complete description was o…

On the characters of the Sylow p-subgroups of untwisted Chevalley groups Y_n(p^a)

Frank Himstedt, Tung Le, Kay Magaard

Let be a Sylow p-subgroup of an untwisted Chevalley group of rank n defined over where q is a power of a prime p. We partition the set $Irr(UY_n(q…

Restricting unipotent characters in special orthogonal groups

Frank Himstedt, Felix Noeske

For all prime powers q we restrict the unipotent characters of the special orthogonal groups SO_5(q) and SO_7(q) to a maximal parabolic subgroup. We determine all irreducible const…

Decomposition numbers of SO_7(q) and Sp_6(q)

Frank Himstedt, Felix Noeske

We complete the l-modular decomposition numbers of the unipotent characters in the principal block of the special orthogonal groups SO_7(q) and the symplectic groups Sp_6(q) for al…

Dade's Invariant Conjecture for the Ree groups 2F4(q^2) in Defining Characteristic

Frank Himstedt, Shih-chang Huang

We verify Dade's invariant conjecture for the simple Ree groups 2F4(2^{2n+1}) for all n > 0 in the defining characteristic, i.e., in characteristic 2. This completes the proof of D…

Characters of the Sylow p-Subgroups of the Chevalley Groups D_4(p^n)

Frank Himstedt, Tung Le, Kay Magaard

Let be a Sylow -subgroup of the Chevalley groups where is a power of a prime . We describe a construction of all complex irreducible characters of …
