After an an overview of the Elliott program; he covers homomorphisms from subhomogeneous C*-algebras to finite dimensional C*-algebras, the stable version of the basic homotopy lemma, a concrete version of the Bott map, a version of the basic homotopy lemma in finite dimensional C*-algebras, the notation of gTR(A)&lt;=1, the classification of C*-algebras with gTR(A)&lt;=1, the basic homotopy lemma in C*-algebras with gTR(A)&lt;=1, a theorem concerning how to lift KK-elements to homomorphisms, the notation of asymptotic unitary equivalence, and some current developments in the Elliott program (without full proofs).
The following Lemma is due to Lemma 3.3 of Leipus and Siaulys (2007).
Since [E.sub.3)](1; F') = [E.sub.3)](1; G') by Lemmas 2.2,2.3,2.4 and 2.7 we get f [equivalent to] g.
By Lemma 3, we obtain that [b.sub.5] (G) = -4n + 10 - 2[c.sub.5] (G).
Lemma 5 will be used to develop test functions needed for the proof of the converse.
By this method, we finally obtain the vertex set [[union].sub.n[greater than or equal to]0] [FT.sub.n] = Q [intersection] [0, 1] of the Farey tree; see [8, Lemma 2.4].
To see that u and v have indeed subharmonic extensions to (EQ) , we use our Lemma 2 as follows.
If [B.sub.12] = b[E.sub.12] and [B.sub.21] = c'[E.sub.21], apply Lemma 2.3 (3) to [B.sub.21] - [B.sub.12], then b, c' [member of] R.
