Spectral Theory and Differential Operators

David Edmunds and Des Evans


This book gives an account of those parts of the analysis of closed linear operators acting in Banach or Hilbert spaces that are relevant to spectral problems involving differential operators, and makes applications to such questions. After the exposition of the abstract theory in the first four chapters, Sobolev spaces are introduced and their main properties established. The remaining seven chapters are largely concerned with second-order elliptic differential operators and related boundary-value problems. Particular attention is paid to the spectrum of the Schrödinger operator. Its original ... More

Keywords: closed linear operator, Banach space, Hilbert space, elliptic differential operator, spectrum, Sobolev space
