Alcuni risultati di analisi spettrale per l’operatore di Laplace su insiemi non limitati

  • Gianfranco Bottaro


In this work I study the spectrum and a system of generalized eigenfunctions for Laplace’s operator in unbounded domains: the plane, the half plane, the plane layer, the exterior of a sphere.
