Further results on permutation polynomials of the form (x(pm) - x plus delta)(s) + L(x) over F-p2m

摘要

Several classes of permutation polynomials with given form over F-p2m were recently proposed by Tu, Zeng, Li and Helleseth. In this paper, continuing their work, we present more permutation polynomials of the form (x(pm) - x + delta)(s) + L(x) over the finite field F-p2m, where L(x) is a linearized polynomial with coefficients in F-p.
