Title
The Spectral Shift Function
Publication Name
Lecture Notes in Mathematics
Abstract
As we noted in the introduction the underlying philosophy is that to go beyond the Fredholm case we need a new perspective on index theory. As the spectral shift function calculates spectral flow in the Fredholm case, we regard it as the natural generalisation of spectral flow to the non-Fredholm case because it remains defined without Fredholm assumptions. In this chapter we introduce the spectral shift function and some of its history.
