Recommended literatureThe lecture notes available (here form the basic source. The literature recommended in SIS is the following: More precisely: The first two topics - Banach algebras and C*-algebras - are more or less covered by Chapters 10 and 11 of [1]. The third and the fourth topics - unbounded operators and spectral decompositions - are inspired mainly by Chapters 12 and 13 of [1] and by Chapters 18-21 of [2]. The correspondence is not exact, moreover, the approaches in the two books differ in several points. |
