Isospectral potentials on a discrete lattice. III


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

Abstract

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.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
