摘要:
我们研究如下问题的径向解,该问题与微机电系统(Micro-Electromechanical Systems, MEMS)的研究相关:方程为-ΔU=(λ+δ|∇U|²)/(1-U),在区域B内U>0,在边界∂B上U=0。其中B⊂ℝᴺ(N≥2)表示开单位球,λ、δ>0为实数。本文考虑两类解:(i)正则解,满足在B内0<U<1;(ii)破裂解,满足U(0)=1,因此方程在原点处奇异。本文还讨论了关于参数λ>0的分岔现象。
英文摘要:
We investigate radial solutions for the problem \[ \begin{cases} \displaystyle -ΔU=\frac{λ+δ|\nabla U|^2}{1-U},\; U>0 & \textrm{in}\ B,\\ U=0 & \textrm{on}\ \partial B, \end{cases} \] which is related to the study of Micro-Electromechanical Systems (MEMS). Here, $B\subset \mathbb{R}^N$ $(N\geq 2)$ denotes the open unit ball and $λ, δ>0$ are real numbers. Two classes of solutions are considered in this work: (i) {\it regular solutions}, which satisfy $0<U<1$ in $B$ and (ii) {\it rupture solutions} which satisfy $U(0)=1$, and thus make the equation singular at the origin. Bifurcation with respect to parameter $λ>0$ is also discussed.
