Entire solutions for a reaction–diffusion equation with doubly degenerate nonlinearity [PDF]

open access: yesAdvances in Difference Equations, 2018
This paper is concerned with the existence of entire solutions for a reaction–diffusion equation with doubly degenerate nonlinearity. Here the entire solutions are the classical solutions that exist for all (x,t)∈R2 $(x,t)\in \mathbb{R}^{2}$.

Entire solutions of nonlinear differential-difference equations. [PDF]

open access: yesSpringerplus, 2016
In this paper, we describe the properties of entire solutions of a nonlinear differential-difference equation and a Fermat type equation, and improve several previous theorems greatly. In addition, we also deduce a uniqueness result for an entire function f(z) that shares a set with its shift [Formula: see text], which is a generalization of a result ...

Entire solutions for the heat equation

open access: yesElectronic Journal of Differential Equations, 2021
We consider the solutions of the heat equation $$ \partial_t F = \partial_z^2 F $$ which are entire in z and t (caloric functions). We examine the relation of the z-order and z-type of an entire caloric function \(F(t, z)\), viewed as function of z, to its t-order and t-type respectively, if it is viewed as function of \(t\). Also, regarding the zeros \

Existence of entire solutions of some non-linear differential-difference equations [PDF]

open access: yesJournal of Inequalities and Applications, 2017
In this paper, we investigate the admissible entire solutions of finite order of the differential-difference equations ( f ′ ( z ) ) 2 + P 2 ( z ) f 2 ( z + c ) = Q ( z ) e α ( z ) $(f'(z))^{2}+P^{2}(z)f^{2}(z+c)=Q(z)e^{\alpha(z)}$ and ( f ′ ( z ) ) 2 + [

Entire solutions for a delayed lattice competitive system [PDF]

open access: goldAdvances in Difference Equations, 2019
In this paper, we investigate the existence of entire solutions for a delayed lattice competitive system. Here the entire solutions are the solutions that exist for all (n,t)∈Z×R $(n,t)\in \mathbb{Z}\times \mathbb{R}$. In order to prove the existence, we

Entire solutions of semilinear elliptic equations

open access: yesElectronic Journal of Differential Equations, 2004
We consider existence of entire solutions of a semilinear elliptic equation $Delta u= k(x) f(u)$ for $x in mathbb{R}^n$, $nge3$. Conditions of the existence of entire solutions have been obtained by different authors.

Negatively Invariant Sets and Entire Solutions [PDF]

open access: yesJournal of Dynamics and Differential Equations, 2010
Negatively invariant compact sets of autonomous and nonautonomous dynamical systems on a metric space, the latter formulated in terms of processes, are shown to contain a strictly invariant set and hence entire solutions. For completeness the positively invariant case is also considered. Both discrete and continuous time systems are considered.
