摘要
In this work we obtain a nontrivial estimate for the size of the set of triples (a, b, c) is an element of F(q)* x F(q) x F(q) which correspond to stable quadratic polynomials f(X) = aX(2) + bX + c over the finite field Fq with q odd. This estimate is an improvement of the bound O(q(11/4)) conjectured in a recent work of A. Ostafe and I. Shparlinski. (C) 2010 Elsevier Inc. All rights reserved.
