- 題 目： Wieferich primes and Fermat numbers: Computations and generalizations
- 日 時： 平成 16年 11月 30日(火) 14:40 〜 15:40
- 場 所： 数学科セミナー室 4号館 3階
In this survey of recent computational and theoretical work I will report on the following interrelated topics:
- (1) computational efforts to find new Wieferich and Wilson primes,
- (2) theoretical and computational results on Fermat and Wilson quotients for composite moduli,
- (3) the search for new factors of Fermat numbers, and
- (4) factors of generalized Fermat numbers.
The talk is partly based on various joint work with T. Agoh, R. Brent, R. Crandall, C. van Halewyn, C. Pomerance, and L. Skula.
