Louis Omenyi, Emmanuel Nwaeze & McSylvester Omaba · Asian Research Journal of Mathematics · 2017
The generic simplicity of the spectrum of a Schrödinger-type operator on the n-dimensional torus is studied using the Rayleigh-Schrödinger perturbation theory. The existence of a perturbation potential of the Laplacian is proved and suitable conditions on the potential that guara...
