Abstract: In this talk, I will discuss how the construction of explicit split exact sequences between quantum projective spaces of Arici and Zegers extends to general quantum flag manifolds, based on the graph description of quantum flag manifolds of Brzeziński, Krähmer, Ó Buachalla, and Strung. This leads to an explicit KK-equivalence between quantum flag manifolds and certain classical spaces, given by copies of the complex numbers. Based on joint ongoing work with Enli Chen and Sophie Zegers.
