我们计算平滑平面域上随机波的开节点线数量的渐近期望。我们发现,对于长能量窗口 [0, λ] 和短能量窗口 [λ, λ +1],开放节点线的预期数量与 λ 成正比,渐近为 λ → ∞。我们的结果与 Blum、Gnutzmann 和 Smilansky [4] 在物理学文献中的预测一致。
We compute the asymptotic expectation of the number of open nodal lines for random waves on smooth planar domains. We find that for both the long energy window [0, λ], and the short one [λ, λ +1], the expected number of open nodal lines is proportional to λ, asymptotically as λ → ∞. Our results are consistent with the predictions of Blum, Gnutzmann, and Smilansky [4] in the physics literature.
