流形上的随机Schr“odinger算子

Random Schr"odinger operators on manifolds

Daniel Lenz, Norbert Peyerimhoff, Ivan Veselic'

摘要:

考虑紧致黎曼流形$M = X/Γ$的覆盖$X$上的随机薛定谔算子族.我们提出了几个结果,他们的谱理论,特别是几乎必然常数的谱分量和存在性和非随机性的综合状态密度。我们还勾勒出一个广群为基础的一般框架,允许在不同的上下文中以统一的方式对待随机算子的基本特征。还讨论了进一步的研究课题。

英文摘要:

We consider a random family of Schrödinger operators on a cover $X$ of a compact Riemannian manifold $M = X/Γ$. We present several results on their spectral theory, in particular almost sure constancy of the spectral components and existence and non-randomness of an integrated density of states. We also sketch a groupoid based general framework which allows to treat basic features of random operators in different contexts in a unified way. Further topics of research are also discussed.
