Conference in Number Theory in Honour of Professor H.C. Williams

Saturday May 24, 2003 to Friday May 30, 2003
to be held at The Banff Centre, Banff, Alberta, Canada

Organizing Committee

Michael Jacobson, Calgary
Renate Scheidler, Calgary
Jon Sorenson, Butler

Andreas Stein, UIUC
Gary Walsh, Ottawa


The conference is open to all areas of Number Theory, with emphasis on Computational Number Theory and applications to Cryptography. Researchers in these fields of study are welcomed to participate, as we honour Canada's foremost computational number theorist, whose contributions include results on integer factorization, primality testing, diophantine equations, linear recurrences, the infrastructure of quadratic number fields and function fields, and their applications to Cryptography. Each day of the conference will include one plenary lecture, a number of invited lectures and time has been set aside each day for contributed talks.

Special Lecture

Manindra Agrawal from IITK, who has recently proved the existence of a deterministic polynomial time algorithm for primality testing, will give a special evening lecture at the Banff Center on Sunday May 25, 2003, with a reception to follow in his honour sponsored by RSA Security Inc.
