摘要:

该文给出了量子环上拟微分算子的谱渐近极限公式, 即对量子环上阶数为 $-m < 0$ 的古典拟微分算子 $T \in \mathrm{C}\Psi^{-m}(C^\infty(\mathbb{T}_\theta^d))$, 其谱渐近极限 $\lim_{t \to \infty} t^{\frac{m}{d}} \mu(t, T) $ 为其主象征 $\sigma(T)_{-m}$ 在单位球面上的 $ L_{\frac d m}$ 积分. 这回答了 McDonald 和 Ponge 的文章 [Adv Math, 2023, 412: 108815] 中提出的一个猜想. 作为推论, 该文给出量子环上拟微分算子的 Weyl 律, 包括 Laplace-Beltrami 算子的 Weyl 律.

Abstract:

This paper establishes a spectral asymptotic formula for pseudodifferential operators on the quantum torus. Specifically, for a classical pseudodifferential operator $T \in \mathrm{C}\Psi^{-m}(C^\infty(\mathbb{T}_\theta^d))$ of order $-m < 0$ the spectral asymptotics $\lim_{t \to \infty} t^{\frac{m}{d}} \mu(t, T)$ is given by the $ L_{\frac d m}$-integral of its principal symbol $\sigma(T)_{-m}$ over the unit sphere. This result confirms a conjecture posed by McDonald and Ponge [Adv Math, 2023, 412: 108815]. As a corollary, we derive the Weyal law for pseudodifferential operators on the quantum torus, including the Weyl law for the Laplace-Beltrami operator.

Key words: quantum torus, pseudodifferential operators, spectral asymptotics, weyl law
