报告摘要 Abstract:

It is difficult to determine whether a given polynomial over a finite field is a PP or not, and it is not easy to find the explicit compositional inverse of a random PP, except for several well-known classes of PPs, which have very nice structure.

  In this talk, we will talk about recent progress on PPs and the general method to compute the compositional inverse of a random PP.
