摘要

我们证明,每个 Borel 函数 V :Ω → [ - ∞ , + ∞ ] 定义在开放子集 Ω ⊂ R N 上,会诱导一个分解 Ω = S∪ ⋃ i D i,使得 W 0 1 , 2 ( Ω ) ∩ L 2 ( Ω ;V + d x ) 在 S 上几乎处处为零,并且在每个分量 D i 上存在 - Δ + V 的非负超解,从而得到相关二次型 ∫ D i ( |∇ ξ | 2 + V ξ 2 ) 的非负性。.

An Agmon-Allegretto-Piepenbrink principle for Schrödinger operators.

We prove that each Borel function V : Ω [ - , + ] defined on an open subset Ω R N induces a decomposition Ω = S i D i such that every function in W 0 1 , 2 ( Ω ) L 2 ( Ω ; V + d x ) is zero almost everywhere on S and existence of nonnegative supersolutions of - Δ + V on each component D i yields nonnegativity of the associated quadratic form D i ( | ξ | 2 + V ξ 2 ) . .
