摘要:In this talk, we give a further study on the permutation behavior of polynomials of a special form by considering the number of solutions of certain equations over finite fields. First, four classes of permutation polynomials of the form over are presented. Notably, some necessary and sufficient conditions for this kind of polynomials to permute are provided. Second, we present several classes of permutation polynomials of the form over of odd characteristic, some of which can provide complete permutation polynomials of this form over .
