Kappeler, T (1989). Isospectral potentials on a discrete lattice. III. Transactions of the American Mathematical Society, 314(2):815-824.
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.
