摘要:The degree of a polynomial is an important parameter to study many problems on polynomials over finite fields. Recently, a new notion of the index of a polynomial over a finite field is introduced to study the distribution of permutation polynomials over finite fields. This parameter also turns out to be very useful in studying value set size bounds, character sum bounds, among others. In this talk I will introduce this new index approach and report some recent results on polynomials over finite fields mentioned above.
