Spectral Properties of the iterated Laplacian with a potential in a Punctured Domain


Gulzat Nalzhupbayeva




In the work we derive regularized trace formulas which were established in papers of Kanguzhin and Tokmagambetov for the Laplace and m-Laplace operators in a punctured domain with the fixed iterating order m 2 N. By using techniques of Sadovnichii and Lyubishkin, the authors in that papers described regularized trace formulae in the spatial dimension d = 2. In this note one claims that the formulas are also true for more general operators in the higher spatial dimensions, namely, 2 d 2m. Also, we give the further discussions on a development of the analysis associated with the operators in punctured domains. This can be done by using so called ’nonharmonic’ analysis.
