| Sep 20, 2014 at 23:47 | comment | added | truebaran | Some time ago I posted the following question, concerning K-theory: mathoverflow.net/questions/169270/… One can form the same question but for K-homology instead of K-theory. So what would be the answer: which (pairs of) abelian countable groups can be realized as K-homology groups? | |
| Sep 20, 2014 at 20:31 | comment | added | Alain Valette | I completely agree with Paul. One difficulty of working with dual algebras is illustrated by my old paper: projecteuclid.org/download/pdf_1/euclid.pjm/1102720214 in which I tried to get a new proof of the Pimsner-Voiculescu 6-terms exact sequence... but I could only get a 5-terms sequence! | |
