As we shall see later on, the compact operators can be regarded as “infinitesimal elements” of ?(?), and it is of interest to know what properties of an operator are unchanged by compact perturbations. For instance, an invertible operator does not remain invertible (think of1–|ξ > <ξ| w

The main result, a famous theorem by Shale and Stine- spring, is of foremost importance in physics. Furthermore, it points to the theory of Fredholm modules of Chapter 8, and thus deserves to be counted as

The transition to the noncommutative world entails putting the metric-generating operator front and centre. This modern approach to geometry is played out on a

Having come so far, it would be a pity not to develop fermion quantum dynamics in external fields, which comes straight from the spin representation.
