Determination of a type of permutation trinomials over finite fields, II

Let q be a prime power. We determine all permutation trinomials of F q 2 of the form a x + b x q + x 2 q - 1 ? F q 2 x . The subclass of such permutation trinomials of F q 2 with a , b ? F q was determined in a recent paper 6.
