High energy asymptotics for the perturbed anharmonic oscillator
Artikel i vetenskaplig tidskrift, 2023
In this article, we study the spectral properties of the perturbation of the generalized anharmonic oscillator. We consider a piecewise Holder continuous perturbation and investigate how the Holder constant can affect the eigenvalues. More precisely, we derive several first terms in the asymptotic expansion for the eigenvalues.
