Auf dem Weg zur Zweiten Moderne which the ring will act. We solve here a similar problem: given a ℚ-matrix . in the suitable class, build from it the Butler ..-groups for which . is a base change. The building procedure we give is an algorithm, easy to perform by hand in one-digit ranks.

Von der zweiten Gründerzeit zur Postmoderne a constructive fashion the question when an almost completely decomposable group has non-zero completely decomposable direct summands. A new invariant, the rank-width difference of . at τ, given by . is the exact rank of a maximal τ-homogeneous (completely decomposable) direct summand of .. We show

Groups which are isomorphic to the additive group of their endomorphism rings are called weak .-groups. The purpose of this article is to consider the apparently yet weaker condition that there be a homorphism from . onto the additive grou

https://doi.org/10.1007/978-3-531-90027-8We consider the connection and interplay between some well-known problems in modular group algebras and the structure of simply presented .-groups. New results in both areas are obtained.

Auf dem Weg zur Zweiten ModerneWe will find normal forms of matrices which describe almost completely decomposable groups in the class of uniform groups defined by Dugas and Oxford up to near-isomorphism. This problem is equivalent to the diagonal equivalence of matrices over ℤ.. ℤ.
