Let \(G\) be a group, let \(A=\Aut(G)\) and consider the descending series \(G,K_1(G),K_2(G),\dots,K_m(G),\ldots\), where \(K_m(G)=[K_{m-1}(G), A]\). Whenever \(K_m=1\) for some positive integer \(m\), the authors call \(G\) an \(A\)-nilpotent group. It is clear that if \(G\) is \(A\)-nilpotent, then \(A\) is nilpotent, being the stability group of the

Quiver theories and formulae for nilpotent orbits of Exceptional algebras
We treat the topic of the closures of the nilpotent orbits of the Lie algebras of Exceptional groups through their descriptions as moduli spaces, in terms of Hilbert series and the highest weight generating functions for their representation content.

Some Residual Properties of Finite Rank Groups
The generalization of one classical Seksenbaev theorem for polycyclic groups is obtained. Seksenbaev proved that if G is a polycyclic group which is residually finite p-group for infinitely many primes p, it is nilpotent. Recall that a group G is said to

The t-Fibonacci sequences in the 2-generator p-groups of nilpotency class 2 [PDF]
In this paper, we consider the 2-generator p-groups of nilpotency class 2. We will discuss the lengths of the periods of the t-Fibonacci sequences in these groups.

Let \(G\) be a finite group and order the set of sizes of conjugacy classes of \(G\) decreasingly to obtain what is called the conjugate type vector of \(G\). The authors show by examples that if \(H\) is nilpotent and if \(G\) and \(H\) have the same conjugate type vector, then \(G\) is not necessarily nilpotent.

On the primitive irreducible representations of finitely generated nilpotent groups
We develop some tecniques whish allow us to apply the methods of commutative algebra for studing the representations of nilpotent groups. Using these methods, in particular, we show that any irreducible representation of a finitely generated nilpotent ...

$G$-nilpotent units of commutative group rings [PDF]
summary:Suppose $R$ is a commutative unital ring and $G$ is an abelian group. We give a general criterion only in terms of $R$ and $G$ when all normalized units in the commutative group ring $RG$ are $G$-nilpotent.

On Torsion-by-Nilpotent Groups
Here are the main results of the article under review: Theorem 1.1. Let \(\wp\) be a class of groups, which is closed under taking subgroups and quotients. Suppose that all metabelian groups of \(\wp\) are torsion-by-nilpotent. Then all soluble groups of \(\wp\) are torsion-by-nilpotent. Theorem 1.2. Let \(H\) be a normal subgroup of a group \(G\). If \

Contributions to automorphisms of affine spaces [PDF]
We study aspects of the group G_n of polynomial automorphisms of the affine space A^n, the so-called affine Cremona group. Shafarevich introduced on G_n the structure of an ind-variety, an infinite-dimensional analogon to a (classical) variety.

Equations in nilpotent groups [PDF]
We show that there exists an algorithm to decide any single equation in the Heisenberg group in finite time. The method works for all two-step nilpotent groups with rank-one commutator, which includes the higher Heisenberg groups. We also prove that the decision problem for systems of equations is unsolvable in all non-abelian free nilpotent groups.
