摘要:

我们考虑紧流形上的磁 Laplace 算子,其磁场为常数且非退化。在大磁场极限下,已知特征值会聚成簇,相应特征空间的和称为 Landau 能级。第一能级作为 Kähler 量子化的自然推广已得到深入研究。本文致力于更高能级:我们将其维数计算为 Riemann–Roch 数,研究相关的 Toeplitz 代数,并证明每个能级都同构于由适当辅助丛扭曲的量子化。

英文摘要:

We consider a magnetic Laplacian on a compact manifold, with a constant non-degenerate magnetic field. In the large field limit, it is known that the eigenvalues are grouped in clusters, the corresponding sums of eigenspaces being called the Landau levels. The first level has been studied in-depth as a natural generalization of the Kaehler quantization. The current paper is devoted to the higher levels: we compute their dimensions as Riemann-Roch numbers, study the associated Toeplitz algebras and prove that each level is isomorphic with a quantization twisted by a convenient auxiliary bundle.
