Ozawa proved (in 2007) that the reduced C*-algebra C r ∗ (F n ) of the free group F n on n generators
can be embedded into a nuclear C*-algebra that is contained in the injective envelope of C r ∗ (F n ).
This provides a rather tight nuclear embedding of C r ∗ (F n ). He furthermore conjectured that it
should be possible to construct such an embedding for any exact C*-algebra. We prove Ozawas
conjecture for the reduced C*-algebra of every discrete exact group.
This is joint work with Matthew Kennedy.
