具有矩阵势的薛定谔算子。从绝对连续谱到奇异谱的过渡

Schrödinger operators with matrix potentials. Transition from the absolutely continuous to the singular spectrum

Stanislav A. Molchanov, Boris R. Vainberg

摘要:

证明了当(矩阵)势平方可积时,矩阵薛定谔算子的绝对连续谱(考虑重数)与未扰动算子的谱重合.同样的结果也证明了一些类的缓慢衰减的潜力,如果他们是光滑的。

英文摘要:

It is proven that the absolutely continuous spectrum of matrix Schrödinger operators coincides (with the multiplicity taken into account) with the spectrum of the unperturbed operator if the (matrix) potential is square integrable. The same result is also proven for some classes of slower decaying potentials if they are smooth.
