Transitive riemannian isometry groups with nilpotent radicals

(See [10] for the definition and precise statement; in the current context, the definition is given in Section 3.7.) In combinatorics, Green and Tao [5] have recently given a

Once established, the converse then enables us to develop a theory of P -isomorphisms of nilpotent groups which parallels.. standard results on nilpotent

On the other hand, the infinite radical rad’(mod A) is not right or left T-nilpotent for the known nondomestic tame algebras A.. We conjecture that all algebras A

On the one hand, in the case of nilpotent Lie groups equipped with left-invariant Riemannian distances the result is essentially known from the work of Wolf, see [Wol63, Wil82]

In particular, the local nature of G=P as a nilpotent stratified Lie group stemming from the Iwasawa decomposition of G ˆ KAN and from the Bruhat decomposition, together with the

Let G be a finitely generated hyperabelian group in which every infinite subset contains a pair of elements generating a polycyclic group.. Then G is

A nilpotent p-group G is supplemented if and only if G is the extension of an abelian artinian group by a group of finite
