  III. Subject and form of proposed joint work (a few phrases)

"Additive Galois module structure of local fields and algebraic number fields"
In particular, we want to investigate the Galois module structure of the ring
of algebraic integers with respect to relative abelian extensions of (local or
global) number fields. Both participants of this project did already some
research work on explicit results on this theme, and now want to combine their
experiences and results for a joint research work.


   IV. Desired duration:

approx. 1 week in the period between Friday, 17.4.1998, and Sunday, 26.4.1998.
The exact dates also depend on the available flights.
