摘要
我们用主符号Hamilton流的递推集的体积证明了半经典拟微分算子的Weyl余数的一般估计。这量化了Volovoy的早期结果（Comm偏微分方程15:1509-15631990；Ann Global Anal Geom 8:127-1361990）。我们的结果特别改进了紧致李群和公转曲面的Weyl余数指数。并根据测地流的最大展开率和拓扑熵，给出了Bérard的Weyl余数的定量估计。
We prove a general estimate for the Weyl remainder of an elliptic, semiclassical pseudodifferential operator in terms of volumes of recurrence sets for the Hamilton flow of its principal symbol. This quantifies earlier results of Volovoy (Comm Partial Differential Equations 15:1509–1563, 1990; Ann Global Anal Geom 8:127–136, 1990). Our result particularly improves Weyl remainder exponents for compact Lie groups and surfaces of revolution. And gives a quantitative estimate for Bérard’s Weyl remainder in terms of the maximal expansion rate and topological entropy of the geodesic flow.
