Remarks on "Resolving isospectral `drums' by counting nodal domains"
摘要：
在[3]中，作者研究了Conway和Sloane发现的等谱平坦4-环面T^ \pm（a，b，c，d）的4参数族.通过计算节点域的特定方法，他们能够通过计算相对于几个显式元组（a，b，c，d）的相应节点序列来区分这些环面（数值上）。在本文中，我们通过分析证明它们的结点数区分任何不同的正实数的4元组来确认[3]中表达的期望。
英文摘要：
In [3] the authors studied the 4-parameter family of isospectral flat 4-tori T^\pm(a,b,c,d) discovered by Conway and Sloane. With a particular method of counting nodal domains they were able to distinguish these tori (numerically) by computing the corresponding nodal sequences relative to a few explicit tuples (a,b,c,d). In this note we confirm the expectation expressed in [3] by proving analytically that their nodal count distinguishes any 4-tuple of distinct positive real numbers.
