摘要
设 Ω⊂R^n 为光滑有界域。在本文中,我们证明了一个结果,其推论如下:令 q∈]0,1[,α∈L^∞(Ω) 且 α>0,k∈N。则问题 \cases {-\tan\left(\int_{\Omega}|\nabla u(x)|^2dx\right)\Delta u= \alpha(x)u^q & in $\Omega$\cr & \cr u>0 & in $\Omega$\cr & \cr u=0 & on $\partial \Omega$ \cr & \cr (k-1)\pi<\int_{\Omega}|\nabla u(x)|^2dx<(k-1)\pi+{{\pi}\over {2}} \cr} 具有唯一的弱解 \tilde u,它是泛函 在 H^1_0(Ω) 中的唯一全局极小,其中 u^+=\max\{0,u\}。
