摘 要:
We cover the basic results of spectral theory. The mostimportant of these are the non-emptiness of the spectrum, Beurling's spec-tral radius formula, and the Gelfand representation theory for commutativeBanach algebras. We also introduce compact and Fredholm operators andanalyse their elementary theory. Important concepts here are the essentialspectrum and the Fredholm index.
