摘要：

Let l be a prime number and let k = F-q be a finite field of characteristic p not equal l with q = p(f) elements. Let n >= 0. We determine the number N of solutions (x, y) in k of the Kummer equation y(l)= x(x(ln)-1), in terms of the trace of a certain Jacobi sum. (C) 2014 Elsevier Inc. All rights reserved.
