Quasidiagonal extensions and sequentially trivial asymptotic homomorphisms, by Vladimir Manuilov and Klaus Thomsen
We obtain a description of the group Pext(K_*(A),K_*(B)) in terms of
extensions of SA by B. For this purpose we introduce the notion of asymptotic
homomorphisms which are sequentially trivial.
