%0 Journal Article %T On Polynomials of the Form %A Amir Akbary %A Qiang Wang %J International Journal of Mathematics and Mathematical Sciences %D 2007 %I Hindawi Publishing Corporation %R 10.1155/2007/23408 %X We give a general criterion for permutation polynomials of the form xrf(x(q−1)/l), where r≥1, l≥1 and l∣(q−1). We employ this criterion to characterize several classes of permutation polynomials. %U http://www.hindawi.com/journals/ijmms/2007/023408/abs/
