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 Ozawa’s conjecture for the reduced C*-algebra of every discrete exact group. This is joint work with Matthew Kennedy.
