Uniqueness theorems concerning L-functions and weakly weighted sharing

Abstract

In this paper, we establish some uniqueness theorems when p(L) and P(L) share “(R(z),l)” where p, P and R denote polynomial function, homogeneous differential polynomial function and rational function respectively and L denotes an L-function in the extended Selberg class. Our results improve and generalize some recent results due to Mandal, Datta [11].
