Pullback of quantum principal bundles
Francesco D'Andrea, Tomasz Maszczyk
We introduce an abstract framework of Cartesian squares beyond the context of fiber products, and use it to extend the notion of pullback from classical to compact quantum principa…

Quantum CW-complexes in a Waldhausen category for unital C*-algebras
Francesco D'Andrea, Piotr M. Hajac, Tomasz Maszczyk +2
Using the ring structure of the K-groups of finite CW-complexes, Atiyah and Todd unravelled the K-theory of complex projective spaces . Herein, in the realm of noncommutative…

An equivariant pullback structure of trimmable graph C*-algebras
Francesca Arici, Francesco D'Andrea, Piotr M. Hajac +1
We prove that the graph C*-algebra of a trimmable graph is -equivariantly isomorphic to a pullback C*-algebra of a subgraph C*-algebra and the C*-alge…
