The Local Asymptotics of Continuum Eigenfunciton Expansions Academic Article uri icon


  • Two theses are advanced: (1) The study of “spectral invariants” can and should be extended to operators with continuous spectra. (2) The subject is closely related to the asymptotic approximation of eigenfunctions by a local amplitude and a phase integral. This program has been carried out in the case of vector-valued functions of one variable. © 1981, North-Holland Publishing Company
