针对 d≥2 维实空间上有界实值势的周期薛定谔算子,研究证明一般势下谱隙端点的布洛赫带达到性质,证实了谱边猜想。
AI中文摘要:
对于定义在 d≥2 的 d 维实空间上、具有有界实值势的周期薛定谔算子 H_V=-Δ+V,我们证明,对于一般势,每个谱隙的端点仅由单个布洛赫带在有限个准动量处达到,且在每个达到点处具有非退化的黑塞矩阵,这证明了周期薛定谔算子的谱边猜想。
英文摘要:
For periodic Schrödinger operators $H_V=-Δ+V$ with bounded real-valued potentials on $\mathbb R^d$ with $d\ge2$, we show that for generic potentials, each endpoint of every spectral gap is attained by a single Bloch band at only finitely many quasimomenta, and has a nondegenerate Hessian at every attaining point. This proves the Spectral Edge Conjecture for periodic Schrödinger operators.
