Abstrakt: We classify all permutation polynomials of the form x 3 g (x q - 1) of F q 2 where g (x) = x 3 + b x + c and b , c ∈ F q ∗ . 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. [ABSTRACT FROM AUTHOR]
