通过交替共振实现几乎Mathieu算子的尖锐谱转变

The Sharp Spectral Transition for Almost Mathieu Operators via Alternating Resonances

Jiawei He, Xueyin Wang

AI总结:

该研究通过交替共振方法,证明了几乎Mathieu算子在特定条件下呈现Anderson局域化,解决了相关文献中的猜想。

AI中文摘要:

我们证明,对于任意给定的频率共振指数和相位共振指数,存在恰好实现这些值的频率与相位,使得当ln|λ|>max{β(α),δ(α,θ)}时,几乎Mathieu算子呈现Anderson局域化,这解决了文献[MR4686650]中的猜想。

英文摘要:

We prove that for any given frequency resonance exponent and phase resonance exponent, there exist a frequency and a phase exactly realizing these values such that the Almost Mathieu operator exhibits Anderson localization for $\ln|λ|>\max\{β(α),δ(α,θ)\}$. This resolves the conjecture in \cite{MR4686650}.
