Résumé:
roughout this paper, we assume that the reader is familiar with the fundamental results and the standard notations of the Nevanlinna value distribution theory (see [1–4]). In addition, we will use 𝜆𝜆𝐴𝑓𝑓𝐴 and 𝜆𝜆𝐴𝑓𝑓𝐴 to denote, respectively, the exponents of convergence of the zero sequence and distinct zeros of a meromorphic function 𝑓𝑓, 𝜌𝜌𝐴𝑓𝑓𝐴 to denote the order of growth of 𝑓𝑓.
