AI总结:

研究了$ p $-Laplace算子在一般开集上的低特征值问题,证明了特定条件下的特征值存在性及特征函数的指数衰减性质。

摘要:

我们考虑了在欧几里得空间一般开集上约束的$p$-Dirichlet积分的minmax Ljusternik-Schnirelmann水平。我们证明,当这些水平低于由$L^p$Poincaré常数"at infinity"给出的阈值时,实际上定义了Dirichlet$p$-Laplace算子的特征值。我们还证明了相关特征函数在无穷远处呈指数衰减:这可以视为非线性情况下的Šnol-Simon型估计。最后,我们展示了一些特殊例子的无界开集,这些开集适用于我们的主要结果。

英文摘要:

We consider the minmax Ljusternik-Schnirelmann levels of the constrained $p-$Dirichlet integral, on a general open set of the Euclidean space. We show that, whenever one of these levels lies below the threshold given by the $L^p$ Poincaré constant ``at infinity'', it actually defines an eigenvalue of the Dirichlet $p-$Laplacian. We also prove an exponential decay at infinity for the relevant eigenfunctions: this can be seen as a Šnol-Simon--type estimate for the nonlinear case. Finally, we exhibit some peculiar examples of unbounded open sets to which our main result applies.
