Nonlinear differential polynomials sharing certain value or fixed point (Q331597)

The authors mainly work on uniqueness problems of meromorphic functions whose certain nonlinear polynomials share certain value or fixed point counting multiplicity. They improve the results of the reviewer and \textit{S. R. Kabbur} [Tamkang J. Math. 44, No. 1, 11--22 (2013; Zbl 1295.30068)]. They again indicate the utility of the notion of the order of multiplicity of the zeros and poles under consideration. They give also significant improvements of earlier results.
