Determination of a Type of Permutation Trinomials over Finite Fields, II

الأصل · EN

Let q be a prime power. We determine all permutation trinomials of Fq₂ of the form ax+bxq+x²q⁻¹∈ Fq₂[x]. The subclass of such permutation trinomials of Fq₂ with a,b∈ Fq was determined in a recent paper by the author.
