在学习立体几何时,有些同学往往受平面几何的影响,把平面几何中成立的一些结论照搬过来,结果造成错解,现举例如下以引起我们的警戒.[例1]如图1,正方形ABCD-A1B1C1D1的棱长为a,M,N分别是棱AA1和CC1上的动点,且AM=C1N 相似文献

p阶平均曲率算子Dirichlet问题的无穷多个解 总被引:1,自引:0,他引:1
§ 1 IntroductionSince the Mountain Pass Theorem came out,the existence of nontrivial solutions,pos-sibly multiple,ofnonlinear elliptic equations has been extensively studied.In this paper,weconsider the following Dirichlet problem for p-(generalized) mean curvature operator:-div((1 +| u|2 ) p- 22 u) =f(x,u) , x∈Ω,u∈ W1 ,p0 (Ω ) , (1 .1 )whereΩ is a bounded domain in Rn(n>p>1 ) with smooth boundary Ω.First let us recall the following Dirichletproblem for p-Laplacian:-Δpu≡ -div… 相似文献

The Hardy-Sobolev inequality with general weights is established, and it is shown that the constant is optimal. The two weights in this inequality are determined by a Bernoulli equation. In addition, the authors obtain the Hardy-Sobolev inequality with general weights and remainder terms. By choosing special weights, it turns to be many versions of the Hardy-Sobolev inequality and the Caffarelli-Kohn-Nirenberg inequality with remainder terms in the literature. 相似文献
