| Abstract: |
| Let f is a transcendental meromorphic function, the value distribution of fPn[f(k)] is discussed.It is proved that fPn[f(k)] takes any finite non-zero complex number infinity under appropriate conditions. |
| Key words: meromorphic function differential polynomials value distribution |
