Uniqueness of differential difference polynomials of L-functions and meromorphic functions sharing a polynomial

In this article, we study the uniqueness of Differential difference polynomials of L-function and Differential difference polynomials of a meromorphic function concerning weighted sharing of a polynomial. Our result improves and generalizes results of Abhijit Banerjee, Saikat Bhattacharyya [1], N. Mandal, N. K. Datta [5].
