Zusammenfassung

From the reviews:

"The book contains 39 articles about computational algebraic number theory, arithmetic geometry and cryptography. ... The articles in this book reflect the broad interest of the organizing committee and the participants. The emphasis lies on the mathematical theory as well as on computational results. We recommend the book to students and researchers who want to read about current research in number theory and arithmetic geometry and its applications." (R. Carls, Nieuw Archief voor Wiskunde, Vol. 6 (3), 2005)
