Value sets of certain maps over finite fields
Ömer Küçüksakallı

Özet : For an arbitrary polynomial, there is no easy formula giving the cardinality of the value set over finite fields. However Chou, Gomez-Calderon and Mullen achieve finding a formula for Dickson polynomials. In this talk we will give two alternative proofs of this formula. These alternative proofs can be generalized to compute the cardinality of the value sets of Lattès maps and bivariate Chebyshev maps.
