Let p denote a prime number and let κp denote the finite field ofp elements. Let f(x) ∊ κp[x] be of fixed degree d ≥ 2. We supposethat p is also fixed, large compared with d, say, p ≥ p0(d). ByV(f) we denote the number of distinct values of f(x), x ∊ κp. Wecall f maximal if V(f) = p and quasi-maximal if V(f) = p + O(1). Clearly amaximal polynomial is quasi-maximal but it is not known under whatconditions the converse holds.
