" Rational Function Analogue of Dickson Polynomials"
Abstract: We give an alternative computation of the value set of Dickson polynomials by using a singular elliptic curve. Our method is not only simpler but also it can be generalised to the non-singular elliptic case. We determine the value set of rational functions related with isogenies of elliptic curves with complex multiplication.
