Abstract
We give an alternative computation of the value sets of Dickson polynomials over finite fields by using a singular cubic curve. Our method is not only simpler but also it can be generalized to the non-singular elliptic case. We determine the value sets of Lattès maps over finite fields which are rational functions induced by isogenies of elliptic curves with complex multiplication.
