摘要
在d维晶格Zd, d = 1,2上,考虑了由Dirac函数和移位算子构造的具有非局域势的离散Schrödinger算子Hλμ。导出了算子的负特征值对参数的依赖关系。
On negative eigenvalues of the discrete Schrödinger operator with non-local potential
On the d-dimensional lattice Zd, d = 1, 2 the discrete Schrödinger operator Hλμ with non-local potential constructed via the Dirac delta function and shift operator is considered. The dependency of negative eigenvalues of the operator on the parameters is explicitly derived.
