Abstract. Given a graph of C*-algebras as defined in [FF13], we prove a long exact sequence in KK-theory similar to the one obtained by Pimsner in [Pi86] for both the maximal and reduced fundamental C*-algebras of the graph in the presence of possibly non-GNS-faithful conditional expectations. In particular, our results give a long exact sequence in KK-theory for both maximal and reduced amalgamated free products and HNN-extensions. In the course of the proof, we established the KK-equivalence between the full amalgamated free product of two unital C*-algebras and a newly defined reduced amalgamated free product that is valid even for non GNS-faithful conditional expectations. This KK-equivalence is again true in the general context. Our re...
