Galois module structure deals with the construction of algebraic invariants from a Galois extension of number fields with group \(G\). Typically these invariants lie in the classgroup of some groupring of \(G\) or of a related order. These classgroups have “Homdescriptions” in terms of idèlicvalued functions on the complex representations of \(G\). Following a theme pioneered by A. Frölich, T. Chinburg constructed several invariants whose Homdescriptions are (conjecturally) given in terms of Artin root numbers. For a tame extension, the second Chinburg invariant is given by the ring of integers, and M. J. Taylor proved the conjecture in this case. The first published graduate course on the Chinburg conjectures, this book provides the necessary background in algebraic and analytic number theory, cohomology, representation theory, and Homdescriptions. The computation of Homdescriptions is facilitated by Snaith's Explicit Brauer Induction technique in representation theory. In this way, illustrative special cases of the main results and new examples of the conjectures are proved and amplified by numerous exercises and research problems. The final chapter introduces a new invariant constructed from algebraic \(K\)theory, whose Homdescription is related to the \(L\)function value at \(s = 1\).

Reviews

This is an advanced text ... However, the author does make plain what he requires and gives sources. He also provides a good introduction to the book as a whole and to its various topics, so that the reader knows the line of argument. There are many explicit examples, and exercises are provided for each chapter ...The book will also be invaluable as introductory reading for a student working in isolation, and it should find its way to the bookshelves of all who work with Galois modules.
Mathematical Reviews 
It will be useful for specialists inside and outside of this subject, as well as for graduate students.
Zentralblatt MATH 
Should be useful to mathematicians who are interested in learning about certain aspects of the theory of arithmetic Galois module structure, as well as to specialists in the area.
