The author proves the following: Theorem. Let f and g be two nonconstant entire functions. Assume that f and g have the same zeros with the same multiplicities and that \(f^{(n)}\) and \(g^{(n)}\) have the same 1- points with the same multiplicities, where n is a nonnegative integer and \(\delta (0,f)>\). Then \(f^{(n)},g^{(n)}=1\) unless \(f\equiv g\).
