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

Non-real zeros of derivatives of real meromorphic functions [PDF]
The main result of the paper determines all real meromorphic functions of finite order in the plane for which the first derivative has finitely many zeros, while the function itself and one of its higher derivatives have finitely many non-real zeros.

Distribution of Normalized Zero-Sets of Random Entire Functions with Small Random Perturbation [PDF]
In this paper, we extend our earlier result (see [Y-2008]) on the distribution of normalized zero-sets of random entire functions to random entire functions with small random perturbation.

Differential polynomials of L-functions with truncated shared values
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.

Operator Bezoutiant and Roots of Entire Functions, Concrete Examples [PDF]
In this paper we use the Bezoutiant method to describe the conditions under which two entire functions have not common roots. We apply the general results to concrete examples. In particular we consider the Bessel functions.

Reminiscence Of An Open Problem: Remarks On Nevanlinna's Four-Value-Theorem [PDF]
The aim of this paper is to describe the origin, first solutions, further progress, the state of art, and a new ansatz in the treatment of a problem dating back to the 1920's, which still has not found a satisfactory solution and deserves to be better known.

Further results on normal families of meromorphic functions concerning shared values [PDF]
In this paper, we prove two normality criteria for families of some functions concerning shared values, the results generalize those given by Hu and Meng. Some examples are given to show the sharpness of our results.
