We propose to discuss here certain spectral properties of Schrödinger operators H=-D+V(x) (D the Laplacian and V a potential) which have application to scattering theory. We consider an operator H with potential V of class SR. We show that the positive point spectrum of H is a discrete set in R+. Eigenfunctions which correspond to positive eigenvalues are shown to decay rapidly. This property is shown to hold also for generalized eigenfunctions. We then establish the limiting absorbing principle, which is a basic tool in our study.\u003c\/p\u003e \u003ch3\u003eDetails\u003c\/h3\u003e \u003cp\u003ePublished by: Edizioni della Normale\u003c\/p\u003e \u003cp\u003ePublication Date: 1975-10-01\u003c\/p\u003e \u003cp\u003eFormat: Paperback\u003c\/p\u003e \u003cp\u003eISBN-13: 9788876422478\u003c\/p\u003e \u003cp\u003eDOI: \u003c\/p\u003e \u003cp\u003eDimensions: 240.0cm x170.0cm\u003c\/p\u003e \u003cp\u003ePages: 68.0\u003c\/p\u003e ","brand":"Scuola Normale Superiore","offers":[{"title":"Default Title","offer_id":44559070691468,"sku":"9788876422478","price":13.46,"currency_code":"USD","in_stock":true}],"url":"https:\/\/lateknightbooks.com\/products\/9788876422478","provider":"Late Knight Books and Services, LLC","version":"1.0","type":"link"}
