给出了n维半经典Schr dinger算子$-h^2 Delta + V(x)- E$的加权预解估计的初等证明 等式2$,其中$h,,E> 0$。势是真实的值,并且$V$和$partial _r V$在无穷远处表现出长程衰减,并且可以像$r$的足够小的负幂一样增长, 0$。预解范数在h^{-1}中呈指数增长,但在无穷大附近呈线性增长。当$V$是紧支撑的,我们得到线性增长,如果预解式乘以在半径为$CE^{-1/2}$的球之外支撑的权重,对于某些$C> 0$。这种$E$-依赖性是尖锐的,并回答了Datchev和Jin的问题。
We give an elementary proof of weighted resolvent estimates for the semiclassical Schrödinger operator $-h^2 Delta + V(x) - E$ in dimension $n eq 2$, where $h, , E> 0$. The potential is real valued and $V$ and $partial _r V$ exhibit long-range decay at infinity and may grow like a sufficiently small negative power of $r$ as $r o 0$. The resolvent norm grows exponentially in $h^{-1}$, but near infinity it grows linearly. When $V$ is compactly supported, we obtain linear growth if the resolvent is multiplied by weights supported outside a ball of radius $CE^{-1/2}$ for some $C> 0$. This $E$-dependence is sharp and answers a question of Datchev and Jin.
