Localized eigenfunctions in Seba billiards J.P. Keating J. Marklof Brian Winn 2134/15455 https://repository.lboro.ac.uk/articles/journal_contribution/Localized_eigenfunctions_in_Seba_billiards/9388292 We describe some new families of quasimodes for the Laplacian perturbed by the addition of a potential formally described by a Dirac delta function. As an application, we find, under some additional hypotheses on the spectrum, subsequences of eigenfunctions of Ĺ eba billiards that localize around a pair of unperturbed eigenfunctions. 2014-08-06 12:17:24 untagged Mathematical Sciences not elsewhere classified
