Abstract
In this paper, we propose several classes of permutation polynomials with the form (x(pm) - x +delta)(s1) +(x(Pm) - x+delta)(s2) + x over finite fields. The permutation behavior of the proposed polynomials is investigated by the AGW criterion and determination of the number of solutions to certain equations over finite fields. (C) 2018 Elsevier Inc.
