在作者以前工作的基础上，考虑了环面上一个离散形式的薛定谔方程‘拉普拉斯加位势’的谱问题。构造了谱不变量，并利用谱不变量确定了某些非一般势的等谱集。抽象的。在作者以前工作的基础上，考虑了环面上一个离散形式的薛定谔方程‘拉普拉斯加位势’的谱问题。构造了谱不变量，并利用谱不变量确定了某些非一般势的等谱集。
: Continuing prior work of the author, spectral problems for a discretized version of the Schrödinger equation ’Laplacian plus potential’ on the torus are considered. Spectral invariants are constructed and with their help isospectral sets of certain nongeneric potentials are determined. Abstract.
