Nov 7, 2017 at 19:05 | comment | added | Paul Siegel | @ogoah You might check out chapter 10 of Analytic K-homology by Higson-Roe. They show that every elliptic operator determines a K-homology class via the functional calculus, and that the index depends only on this class. The book is written with generalizations to Hilbert modules in mind, though they don't appear explicitly. And yes, the whole construction is in a sense a jazzed-up version of what I wrote above. | |
