| Description |
On 22 and 23 April 2008 a workshop on factoring large numbers with NFS and on DL-problems will take place at the Institute fuer Experimentelle Mathematik in Essen. The workshop is dedicated to present recent results and exchange ideas in these topics concerning both theory, hard- and software aspects.
Everyone interested in these topics is heartily invited to come!
