Abstract

This paper proves the following results: Let f be a transcendental entire function, and let k(¸ 2) be a positive integer. If T(r; f) 6= N1)(r; 1=f)+S(r; f); then ff(k) assumes every finite nonzero value infinitely often. Also the case when f is a transcendental meromorphic function has been considered and some results are obtained.
