Abstract

The normality of a family of meromorphic functions whose differential polynomials satisfy a certain condition is studied. This significantly improves and generalizes some recent results of  Chen (Filomat, 31 (14), 4665–4671, 2017). Moreover, the result is sharp, which is demonstrated with the help of examples.
