“…A first answer to Gelfond's original problem for integer valued polynomials was given by Dartyge and Tenenbaum in [3,4] where they obtained the following general lower bound: Theorem D. Let q and m be positive integers such that q ≥ 2 and gcd(m, q − 1) = 1 and let P ∈ Z[X] be such that P (N) ⊂ N. Then there exist two constants C = C(P, q, m) > 0 and N 0 = N 0 (P, q, m) ≥ 1 such that for any a ∈ {0, 1, . .…”
