| Outline of Final Research Achievements |
In this study, we dealt with the spectral theory on Schroedinger equations, which is a fundamental equation in the field of quantum mechanics. Most of the reuslts on this study are the results on spectra of periodic Schroedinger operators on a hexagonal lattice with cylindrical nanostructure, corresponding to a carbon molecule called a carbon nanotube. In this study, H. Niikuni defined the operator as a self-adjoint differential operators on graph, and examined its spectrum from the point of view of the theory of a quantum graph. On behalf of the paper on the spectra of Schroedinger operators on periodically broken carbon nanotubes, H. Niikuni published 6 related papers during the period of this study.
