Hongxun, Yi, Unicity Theorems for Entire or Meromorphic Functions, Acta Mathematica Sinica, New Series Chinese Journal of Mathematics, 10(2), 1994, pp. 121-131
In this paper, we deal with the problem of uniqueness of entire or meromorphic functions and obtain some results that are improvements over those of M. Ozawa, H. Ueda, K. Shibazaki and Yi Hongxun. An example shows that the results in this paper are sharp.
