 Carlitz–Wan conjecture

The Carlitz-Wan conjecture is a conjecture in number theory related to the distribution of roots of polynomials over finite fields. Specifically, it is concerned with the number of roots of certain families of polynomials in the context of function fields. The conjecture was posed by L. Carlitz and J. Wan and suggests a specific behavior regarding the number of rational points (or roots) of certain algebraic equations over finite fields.
