椭圆型方程模型MEMS解的唯一性

Uniqueness of solutions for an elliptic equation modeling MEMS

Nassif Ghoussoub, Pierpaolo Esposito

摘要:

研究了参数$λ$、维数$N$、轮廓$f$和区域$Ω\subset\mathbb{R}^N$的几何形状对以下具有奇异非线性项的椭圆边值问题解的唯一性问题的影响:$$ 180pt {{array}{ll} -Δu= \frac{λf(x)}{(1-u)^2} & \hbox{in}Ω0<u<1 &\hbox{in}Ωu=0 &\hbox{on}\partial Ω. {array}. 130pt (S)_{λ, f} $$该方程已被提出作为简单静电微机电系统(MEMS)的模型。由薄介电弹性膜组成的器件,其边界支撑在位于高度z = 1的刚性接地板下方的0处。

英文摘要:

We study the effect of the parameter $λ$, the dimension $N$, the profile $f$ and the geometry of the domain $Ω\subset\mathbb{R}^N$, on the question of uniqueness of the solutions to the following elliptic boundary value problem with a singular nonlinearity: $$ 180pt {{array}{ll} -Δu= \frac{λf(x)}{(1-u)^2} & \hbox{in}Ω0<u<1 &\hbox{in}Ωu=0 &\hbox{on}\partial Ω. {array}. 130pt (S)_{λ, f} $$ This equation has been proposed as a model for a simple electrostatic Micro-Electromechanical System (MEMS) device consisting of a thin dielectric elastic membrane with boundary supported at 0 below a rigid ground plate located at height z = 1.
