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…
Rank-two Milnor idempotents for the multipullback quantum complex projective plane
Carla Farsi, Piotr M. Hajac, Tomasz Maszczyk +1
The -group of the C*-algebra of multipullback quantum complex projective plane is known to be , with one generator given by the C*-algebra itself, one given by t…
The K-theory of Heegaard quantum lens spaces
Piotr M. Hajac, Adam Rennie, Bartosz Zielinski
Representing Z/N as roots of unity, we restrict a natural U(1)-action on the Heegaard quantum sphere to Z/N, and call the quotient spaces Heegaard quantum lens spaces. Then we use…
