Constructing permutation polynomials is a hot topic in finite fields. Recently, huge kinds of permutation polynomials over F q 2 have been studied. In this paper, by using AGW criterion and piecewise method, we construct several classes of permutation polynomials over F q 3 of the forms similar to ( x q 2 + x q + x + δ ) q 3 1 d + 1 + L ( x ), for d = 2 , 3 , 4 , 6 , where L ( x ) is a linearized polynomial over F q .
