Results on L-functions whose certain differential polynomials share one finite nonzero value

Abstract

We study a uniqueness question of meromorphic functions whose certain nonlinear differential polynomials share a finite nonzero value   The results in this paper extend the corresponding results from Steuding[12, p.152], Li[7] and Fang[1] of the present paper. The studied question is concerning a question posed by Fang in 2009.
