We study the connection between Massey products and relations in pro-p-groups and give an arithmetical example, thereby obtaining a coho- mological interpretation of the Redei symbol. 1. Masseyprodukte und Relationen in pro-p-Gruppen In diesem Abschnitt verallgemeinern wir den bekannten Zusammenhang zwischen dem Cupprodukt in der Kohomologie von pro-p-Gruppen und Darstellungen von pro-p-Gruppen durch Erzeugende und Relationen.

We announce the creation of a database of invariant rings. This database contains a large number of invariant rings of finite groups, mostly in the modular case. It gives information on generators and structural properties of the invariant rings. The main purpose is to provide a tool for researchers in invariant theory.

As a main tool we prove a Weierstrass preparation theorem for certain skew power series rings. One striking result in our work is the discovery of the abundance of faithful torsion modules, i.e. non-trivial torsion modules whose global annihilator ideal is zero. Finally we show that the completed group algebra with coefficients in the finite field of p elements is a unique factorization domain in the sense of Chatters.
