“Quasidiagonal
Traces
and
Crossed
Products”
A trace on a C*-algebra is quasidiagonal if it can be approximated by traces on finite dimensional C*-algebras through completely positive maps. We will discuss what is known and not known about quasidiagonal traces and give some partial results for traces on crossed product C*-algebras. The strongest results are for crossed products given by integer actions on AF-algebras.
