Pure Maths Colloquium: Albanese mappings: old and new.

Presented by "Tamás Szamuely (Alfréd Rényi Institute of Mathematics, Budapest, Hungary)",

23 October 2000 00:00 in CM221

"A famous theorem of A. A. Roitman states that for a smooth projective variety over an algebraically closed field (of characteristic 0, for simplicity), the so-called Albanese map induces an isomorphism of the torsion subgroup of the Chow group of zero-cycles with the group of torsion points of the Albanese variety. Recently Michael Spiess and I found a new conceptual approach to this theorem which allows a generalisation to not necessarily projective varieties. In the lecture I'll retrace the long and glorious history of the subject starting from classical work of Abel and Jacobi over the complex numbers, before giving a brief explanation of our recent work."
