Shape Theory and Extensions of C*-Algebras
[OWP-2010-16] (Mathematisches Forschungsinstitut Oberwolfach, 2010-03-16)Let A, A' be separable $C^*$-algebras, $B$ a stable $\sigma$-unital $C^*$-algebra. Our main result is the construction of the pairing $[[A', A]] \times Ext^{-1/2}(A,B) \to Ext^{-1/2}(A',B)$, where $[[A', A]]$ denotes the ...
