Uniqueness, Meromorphic function, Non-linear dierential polynomials, normal families.


In this paper, we use the idea of normal family to investigate the uniqueness
problems of meromorphic functions when certain non-linear dierential polynomial sharing
a nonzero polynomial with certain degree. We obtain some results which will not only rectify
the recent results of P. Sahoo and H. Karmakar [9] but also improve and generalize some
recent results of L. Liu [7], H. Y. Xu, T. B. Cao and S. Liu [12] and P. Sahoo and H.
Karmakar [9] in a large extent.
