椭圆算子本征函数的某些Liouville性质
Certain Liouville properties of eigenfunctions of elliptic operators
摘要:
我们提出了一些刘维性质的特征函数的二阶椭圆算子的实系数,通过一种方法,是基于随机表示的正解,和临界理论的二阶椭圆算子。这些结果推广了Y. Pinchover到薛定谔型非对称算子的情况。特别地,我们提供了Pinchover在[Comm.Math.Phys.272(2007),no.1,75-84,问题5]中提出的开放问题的答案。此外,我们证明了一般二阶椭圆算子在任意维上正上解衰减的一个下界,并讨论了它对Landis猜想的意义。
英文摘要:
We present certain Liouville properties of eigenfunctions of second-order elliptic operators with real coefficients, via an approach that is based on stochastic representations of positive solutions, and criticality theory of second-order elliptic operators. These extend results of Y. Pinchover to the case of nonsymmetric operators of Schrödinger type. In particular, we provide an answer to an open problem posed by Pinchover in [Comm. Math. Phys. 272 (2007), no. 1, 75-84, Problem 5]. In addition, we prove a lower bound on the decay of positive supersolutions of general second-order elliptic operators in any dimension, and discuss its implications to the Landis conjecture.
