Deficiencies of differential polynomials
Let \(f\) be a transcendental meromorphic function in the complex plane. Denote by \(P[f]\) a homogeneous differential polynomial in \(f\). The author proves some results on the value distribution of \(P[f']\) mostly under certain conditions on the value distribution of \(f\).
