Weighted set sharing and related uniqueness problems for L-function

Abstract

In this paper, we investigate the uniqueness problem of L-functions belonging to the (extended) Selberg class by considering the weighted set sharing with an arbitrary meromorphic function having finitely many poles. The results obtained in this article significantly extends and also improves in some sense a result of the present authors [Comput. Methods Funct. Theo., 19 (2019), 601-612] and a recent result due to Banerjee-Kundu [Filomat, 36 (2022), 3755-3774].
