Note on Permutation Binomials and Trinomials over Finite Fields
Neranga Fernando · New Zealand journal of mathematics · 2018
Let p be an odd prime and e be a positive integer. We completely explain the permutation binomials and trinomials arising from the reversed Dickson polynomials of the (k + 1)-th kind Dn,k(1,x) over when n = pl + 2, where .
