On value distribution of certain delay-differential polynomials
Nan Li, Lianzhong Yang
Given an entire function of finite order , let be a linear delay-differential polynomial of with small coefficients i…
Some results on transcendental entire solutions of certain nonlinear differential-difference equations
Nan Li, Jiachuan Geng, Lianzhong Yang
In this paper, we study the transcendental entire solutions for the nonlinear differential-difference equations of the forms: $f^{2}(z)+\widetildeω f(z)f'(z)+q(z)e^{Q(z)}f(z+c)=u(z…
On algebraic differential equations concerning the Riemann-zeta function and the Euler-gamma function
Qiongyan Wang, Manli Liu, Nan Li
In this paper, we prove that is not a solution of any non-trivial algebraic differential equation whose coefficients are polynomials in over the ring of p…
Three results on transcendental meromorphic solutions of certain nonlinear differential equations
Nan Li, Lianzhong Yang
In this paper, we study the transcendental meromorphic solutions for the nonlinear differential equations: and $f^{n}+P_{*}(f)=p_{1}(z)e^{α_{1}(z)}+p_{2}(…
Mason's theorem with a difference radical
Katsuya Ishizaki, Risto Korhonen, Nan Li +1
Differential calculus is not a unique way to observe polynomial equations such as . We propose a way of applying difference calculus to estimate multiplicities of the roots…
Difference analogue of Cartan's Second Main Theorem for slowly moving periodic targets
Risto Korhonen, Nan Li, Kazuya Tohge
We extend the difference analogue of Cartan's second main theorem for the case of slowly moving periodic hyperplanes, and introduce two different natural ways to find a difference…
