• 講演者: Karl Dilcher 氏 (Dalhousie 大学)
    • 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.
