The Spectral Theorem

Part of the Graduate Texts in Mathematics book series (GTM, volume 284)


This chapter introduces the notion of the spectrum of an operator (possibly unbounded) on a Hilbert space. The theory of the resolvent operator is developed and used to establish basic properties of the spectrum.
