Existence of entire positive solutions for a class of semilinear elliptic systems

open access: yesElectronic Journal of Differential Equations, 2010
Under simple conditions on $f_i$ and $g_i$, we show the existence of entire positive radial solutions for the semilinear elliptic system $$displaylines{ Delta u =p(|x|)f_1(v)f_2(u)cr Delta v =q(|x|)g_1(v)g_2(u), }$$ where $xin mathbb{R}^N$, $Ngeq ...

Existence and stability properties of entire solutions to the polyharmonic equation $(-Δ)^m u=e^u$ for any $m\ge 1$ [PDF]

open access: yesarXiv, 2014
We study existence and stability properties of entire solutions of a polyharmonic equation with an exponential nonlinearity. We study existence of radial entire solutions and we provide some asymptotic estimates on their behavior at infinity. As a first result on stability we prove that stable solutions (not necessarily radial) in dimensions lower than

The exact entire solutions of certain type of nonlinear difference equations [PDF]

open access: yesarXiv, 2020
In this paper, we consider the entire solutions of nonlinear difference equation $$f^3+q(z)\Delta f=p_1 e^{\alpha_1 z}+ p_2 e^{\alpha_2 z} $$ where $q$ is a polynomial, and $p_1, p_2, \alpha_1, \alpha_2$ are nonzero constants with $\alpha_1\neq \alpha_2$. It is showed that if $f$ is a non-constant entire solution of $\rho_2(f)<1$ to the above equation,

Existence for (p, q) critical systems in the Heisenberg group

open access: yesAdvances in Nonlinear Analysis, 2019
This paper deals with the existence of entire nontrivial solutions for critical quasilinear systems (𝓢) in the Heisenberg group ℍn, driven by general (p, q) elliptic operators of Marcellini types.

Entire solutions to semilinear nonlocal equations in $\RR^2$

open access: yes, 2015
We consider entire solutions to $L u= f(u)$ in $\RR^2$, where $L$ is a general nonlocal operator with kernel $K(y)$. Under certain natural assumtions on the operator $L$, we show that any stable solution is a 1D solution.

Characterizations of transcendental entire solutions of trinomial partial differential-difference equations in ℂ2#

open access: yesDemonstratio Mathematica
This study is devoted to exploring the existence and the precise form of finite-order transcendental entire solutions of second-order trinomial partial differential-difference equations L(f)2+2hL(f)f(z1+c1,z2+c2)+f(z1+c1,z2+c2)2=eg(z1,z2)L{(f)}^{2}+2hL(f)

Entire solutions for nonlinear differential-difference equations

open access: yesElectronic Journal of Differential Equations, 2015
In this article, we study entire solutions of the nonlinear differential-difference equation $$ q(z)f^{n}(z)+a(z)f^{(k)}(z+1)=p_1(z)e^{q_1(z)}+p_2(z)e^{q_2(z)} $$ where $p_1(z)$, $p_2(z)$ are nonzero polynomials, $q_1(z)$, $q_2(z)$ are ...

Entire solutions originating from three fronts to a two-dimensional nonlocal periodic lattice dynamical system [PDF]

open access: yesarXiv, 2019
This paper is concerned with the entire solutions of a two-dimensional nonlocal periodic lattice dynamical system. With bistable assumption, it is well known that the system has three different types of traveling fronts. The existence of merging-front entire solutions originating from two fronts for the system have been established by Dong, Li \& Zhang

Entire holomorphic curves on a Fermat surface of low degree [PDF]

open access: yesarXiv, 2016
The purpose of the paper is to study some problems raised by Hayman and Gundersen about the existence of non-trivial entire and meromorphic solutions for the Fermat type functional equation $f^n+g^n+h^n=1$. Hayman showed that no non-trivial meromorphic solutions and entire solutions exist when $n \ge 9$ and $n \ge 7$ respectively.
