| Abstract: |
|---|
| Uniformly HyperFinite (UHF) algebras are those C*-algebras in which
every finite subset is `near' a finite-dimensional full matrix
subalgebra. This can be formalized in three different ways, all three
being equivalent in the separable case. Separable UHF algebras were
classified in the 1960s by Glimm and Dixmier. Dixmier asked whether the
three definitions are equivalent in the nonseparable case. I will give
a complete answer to this question. One of the methods used is a new
way of associating a C*-algebra to a graph. A part of this work is
joint with Takeshi Katsura. |
