Differential polynomials of L-functions with truncated shared values

open access: yesOpen Mathematics, 2019
In this paper, by using the idea of truncated counting functions, we study the uniqueness of transcendental meromorphic functions and L-functions whose certain nonlinear differential polynomials share one finite nonzero value.

Fixed Points of Meromorphic Functions and Their Higher Order Differences and Shifts

open access: yesOpen Mathematics, 2019
In this paper, we investigate the relationships between fixed points of meromorphic functions, and their higher order differences and shifts, and generalize the case of fixed points into the more general case for first order difference and shift ...
