" Rational Function
Analogue of Dickson Polynomials"
By
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.
