我们证明了Connes和Moscovici所预测的对数Weyl定律,该定律适用于实直线上算子$P=-\partial_x(x^2-1)\partial_x-4\pi^2x^2$的特定自伴扩展的大正特征值。更精确地说,我们使用WKB方法,并展示了一个刻画足够大特征值的Bohr-Sommerfeld量子化规则。一个特别的困难在于相关的依赖于$h$的Lagrangian子流形是非紧的,这需要对作用积分进行重整化。此外,为了处理系数在$x=\pm 1$处的退化,我们使用了基于径向估计和Lagrangian正则性的拟模匹配论证。
英文摘要
We prove the logarithmic Weyl law predicted by Connes and Moscovici for large positive eigenvalues of the distinguished self-adjoint extension of the operator $P=-\partial_x(x^2-1)\partial_x-4π^2x^2$ on the real line. More precisely, we use the WKB method and show a Bohr-Sommerfeld quantization rule characterizing sufficiently large eigenvalues. A particular difficulty is that the associated $h$-dependent Lagrangian submanifolds are non-compact, which requires a renormalization of the action integral. Furthermore, to deal with the degeneracy of the coefficients at $x =\pm 1$, we use a quasimode matching argument based on radial estimates and Lagrangian regularity.
