Algebra and Number Theory (Proceedings of a Conference held at the Institute of Experimental Mathematics, University of Essen (Germany), December 2-4, 1992) ||

The series is aimed specifically at publishing peer reviewed reviews and contributions presented at workshops and conferences. Each volume is associated with a particular conference, symposium or workshop. These events cover various topics within pure and applied mathematics and provide up-to-date coverage of new developments, methods and applications. Strict factorisability and shadows Frobenius order-sequences of curves Discriminants of Hermitian R[G]-modules and Brauer’s class number relation On coverings of elliptic curves On Artin L-series of irreducible characters of the symmetric group Sn Higher Bruhat-Tits buildings and vector bundles on an algebraic surface 1⁄2 Riemann existence theorem with Galois action On a variation of Hilbert’s 17th problem On the local Galois structure of S-units Abelian varieties, p-adic heights and derivatives The Tate conjecture for non-simple abelian varieties over finite fields Ever since Nelson's London Ph.D. (cf. [19]) the notion of factorisability, in one version or another, has been a main tool in investigating arithmetic Galois module structure (cf. [1], [2], [3], [4], [5], [7], [12], [13], [14], [15], [16], [17], [18], [20], [22], [23]).
