Moreover we find new examples of permutation polynomials and we correct some contradictory statements in the recent literature. We assume that gcd(3, q -1) = 1 and we use a well known criterion due to Wan and Lidl, Park and Lee, Akbary and Wang, Wang, and Zieve.eninfo:eu-repo/semantics/closedAccessFinite fieldsPermutation polynomialsAbsolutely irreducibleClassification of permutation polynomials of the form x3g(xq-1) of Fq2 where g(x) = x3 + bx plus c and b, c ∈ Fq*ArticleQ290715371556WOS:000800829500001
