Uniqueness of difference polynomials
Let $ f(z) $ be a transcendental meromorphic function of finite order and $ c\in\Bbb{C} $ be a nonzero constant. For any $ n\in\Bbb{N}^{+} $, suppose that $ P(z, f) $ is a difference polynomial in $ f(z) $ such as $ P(z, f) = a_{n}f(z+nc)+a_{n-1}f(z+(n-1)

Entire functions that share a small function with their linear difference polynomial
In this paper, we investigate the uniqueness of an entire function sharing a small function with its linear difference polynomial. Our results improve some results due to Li and Yi [11], Zhang, Chen and Huang [17], Zhang, Kang and Liao [18,19] etc.

This paper deals with a root condition for polynomial of the second order. We prove the root criterion for such polynomial with complex coefficients. The criterion coincides with well‐known Hurwitz criterion in the case of real coefficients.

This paper deals with a root condition for polynomial of the second degree. We propose the root condition criterion for such polynomial wiith complex coefficients. The criterion coincide with well-known Hurwitz criterion in the case of real coefficients.

Kolmogorov-Arnold-Moser Theory and Symmetries for a Polynomial Quadratic Second Order Difference Equation [PDF]
By using the Kolmogorov-Arnold-Moser (KAM) theory, we investigate the stability of two elliptic equilibrium points (zero equilibrium and negative equilibrium) of the difference equation t n + 1 = α t n + β t n 2 − t n ...

Multivariate Polynomial Values in Difference Sets [PDF]
For $\ell\geq 2$ and $h\in \mathbb{Z}[x_1,\dots,x_{\ell}]$ of degree $k\geq 2$, we show that every set $A\subseteq \{1,2,\dots,N\}$ lacking nonzero differences in $h(\mathbb{Z}^{\ell})$ satisfies $|A|\ll_h Ne^{-c(\log N)^ }$, where $c=c(h)>0$, $ =[(k-1)^2+1]^{-1}$ if $\ell=2$, and $ =1/2$ if $\ell\geq 3$, provided $h(\mathbb{Z}^{\ell})$ contains ...

Alternatives to polynomial trend-corrected differences-in-differences models [PDF]
A common problem with differences-in-differences (DD) estimates is the failure of the parallel-trend assumption.

Uniqueness of entire functions whose difference polynomials share a polynomial with finite weight
In this paper, we use the concept of weighted sharing of values to investigate the uniqueness results when two difference polynomials of entire functions share a nonzero polynomial with finite weight.
