Abstract

In this paper, we study the discrete Kirchhoff–Choquard equation

$$\begin{aligned} -\left( a+b \int _{{\mathbb {Z}}^3}|\nabla u|^{2} d \mu \right) \Delta u+V(x) u=\left( R_{\alpha } *F(u)\right) f(u),\quad x\in {\mathbb {Z}}^3, \end{aligned}$$

where $a,\,b>0$, $\alpha \in (0,3)$ are constants and $R_{\alpha }$ is the Green’s function of the discrete fractional Laplacian that behaves as the Riesz potential. Under some suitable assumptions on V and f, we prove the existence of nontrivial solutions and ground state solutions respectively by variational methods.

离散非线性基尔霍夫-乔夸德方程的解决方案

在本文中，我们研究了离散基尔霍夫-乔夸德方程 $$begin{aligned} -\left( a+b \int _{\mathbb {Z}}^3}|\nabla u|^{2} d \mu \right) \Delta u+V(x) u=\left( R_{\alpha } *F(u) \right*F(u)\right) f(u),\quad x\in {\mathbb {Z}}^3, \end{aligned}$$其中$a,\,b>0$,$\alpha \in (0,3)$ 是常数，$R_{\alpha }$ 是离散分数拉普拉斯函数的格林函数，表现为里兹势。在关于 V 和 f 的一些适当假设下，我们通过变分法分别证明了非小解和基态解的存在性。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
