报告摘要：The security of most public-key cryptography systems is based on the belief that prime factorization of a large integer n cannot be done in polynomial time of log n. This belief, however, has no theoretical or scientific evidence. An increasing number of number theorists, including the speaker, believe that the opposite is actually true. To look for evidence of a possible efficient factorization algorithm, one considers a seemingly simpler question: are there efficient algorithms for the Liouville function λ(n) and/or the Möbius function μ(n)? One hopes that efficient methods to compute λ(n) and μ(n) might be based on their additive properties. The goal of this talk is thus to find additive relations among values of λ(n) and μ(n).
