一类椭圆型偏微分方程及其应用

An elliptic partial differential equation and its application

Dragos-Patru Covei, Traian A. Pirvu

摘要:

本文研究了椭圆型方程\begin{equation*} -2σ^{2}Δz+\left\| \nabla z\right\| ^{2}+4αz=4\left\| x\right\| ^{2}\text{ for }x\in \mathbb{R}^{N}\text{, (}% N\geq 1\text{),} \end{equation*} %,其中$α>0,$、$σ>0$是实参数.该解决方案的方法是基于子和超级解决方案的方法。病例$N>1$之前似乎未考虑。该方程模拟了一个随机生产计划问题。

英文摘要:

This paper deals with the following elliptic equation \begin{equation*} -2σ^{2}Δz+\left\| \nabla z\right\| ^{2}+4αz=4\left\| x\right\| ^{2}\text{ for }x\in \mathbb{R}^{N}\text{, (}% N\geq 1\text{),} \end{equation*}% where $α>0,$ $σ>0$ are some real parameters. The solution method is based on the sub- and super-solutions approach. The case $N>1$ seemed not considered before. This equation models a stochastic production planning problem.
