Unicity Of Meromorphic Mappings

For a given meromorphic function Iz and an arbitrary value a Nevanlinnas value distribution theory which can be derived from the well known PoissonJensen for mula deals with relationships between the growth of the function and quantitative estimations of the roots of the equation 1 z a O. In the 1920s as an application of the celebrated Nevanlinnas value distribution theory of meromorphic functions R. Nevanlinna 188 himself proved that for two nonconstant meromorphic func tions I 9 and five
