ABSTRACT
We study the normal structure of the unipotent radical U of a Borel subgroup in a Lie type group over a field K. Thus, all maximal Abelian normal subgroups in U are described. This gives a new solution of C. Parker and P. Rowley's problem about extremal subgroups in U and the description in finite groups U of the large normal (and, as proved, also normal large) Abelian subgroups.

Let G be a finite group and F be a field. Any linear code over F that is permutation equivalent to some code defined by an ideal of the group ring FG will be called a G-code. The theory of these 'abstract' group codes was developed in 2009. A code is called Abelian if it is an A-code for some...

We show that when G is a finite group that contains an elementary Abelian subgroup of order p2 and k is an algebraically closed field of characteristic p, then the study of simple endotrivial kG-modules that are not monomial may be reduced to the case when G is quasi-simple.

Answering a question of I. M. Isaacs, we show that the largest degree of irreducible complex representations of any finite non-abelian simple group can be bounded in terms of the smaller degrees. We also study the asymptotic behavior of this largest degree for finite groups of Lie type....

Let F be a free Lie algebra of rank n â‰¥ 2 and A be a free abelian Lie algebra of rank m â‰¥ 2. We prove that the test rank of the abelian product F Ã— A is m. Morever we compute the test rank of the algebra $F/\gamma _{k}\left( F\right) ^{^{\prime }}$.

Let $G$ be a simple simply connected complex Lie group. Some criteria are given for the nonexistence of exceptional principal $G$-bundles over a complex projective surface. As an application, it is shown that there are no exceptional $G$-bundles over a surface whose...

In this note we prove that a compact connected Lie group G admits a free action on some product of linear spheres if and only if it is isomorphic to (Tk Ã— SU(2)l)/Z for some k and l and for some central elementary abelian 2-subgroup Z with Z âˆ© SU(2)Ml = 1.

There is a well known principle in classical mechanic stating that a variational problem independent of a space variable w (so called cyclic variable), but dependent on the velocity wâ€² can be expressed without both w and wâ€². This is the Routh reduction principle. We develop a...
