[OWP-2010-16] Manujlov, Vladimir M.; Thomsen, Klaus (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 ...
