在“黑箱”长程扰动的半经典情形下,得到了谱移函数λ(λ)关于两个自伴算子Lj(h),j = 1,2的导数的表示.证明了导数λ ′(λ)由算子Lj(h)的截断预解式的范数估计.最后,我们建立了谱移函数λ(λ)的Weyl型公式,推广了Robert [19]和Christiansen [5]的结果.
We obtain in the semi-classical setup of “black-box” long-range perturbations a representation for the derivative of spectral shift function ξ(λ) related to two self-adjoint operators L j (h), j = 1,2. We show that the derivative ξ′(λ) is estimated by the norms of the cut-off resolvents of the operators L j (h). Finally, we establish a Weyl type formula for the spectral shift function ξ(λ) generalizing the results of Robert [19] and Christiansen [5].
