Lehmer Prizes

Each year at the conference, the organizing committee gives out the Emma and Dick Lehmer prizes: awards given to the committee’s favorite talks of the conference. Traditionally, at least one of these awards is given to a first-time speaker at West Coast Number Theory.

Recipients of the Lehmer Prize are given free registration to participate in next year’s conference.

To date, the recipients have been as follows:
