We find multipullback quantum odd-dimensional spheres equipped with natural $U(1)$-actions that yield the multipullback quantum complex projective spaces constructed from Toeplitz cubes as noncommutative quotients. We prove that the noncommutative line bundles associated to multipullback quantum odd spheres are pairwise stably non-isomorphic, and that the $K$-groups of multipullback quantum complex projective spaces and odd spheres coincide with their classical counterparts. We show that these… 

Associated noncommutative vector bundles over the Vaksman–Soibelman quantum complex projective spaces

By a diagonal embedding of $U(1)$ in $SU_q(m)$, we prolongate the diagonal circle action on the Vaksman-Soibelman quantum sphere $S^{2n+1}_q$ to the $SU_q(m)$-action on the prolongated bundle. Then

Rank-two Milnor idempotents for the multipullback quantum complex projective plane

The $K_0$-group of the C*-algebra of multipullback quantum complex projective plane is known to be $\mathbb{Z}^3$, with one generator given by the C*-algebra itself, one given by the section module

Pulling back noncommutative associated vector bundles and constructing quantum quaternionic projective spaces

Our main theorem is that the pullback of an associated noncommutative vector bundle induced by an equivariant map of quantum principal bundles is a noncommutative vector bundle associated via the

The K-theory type of quantum CW-complexes

The multipullback quantization of complex projective spaces lacks the naive quantum CW-complex structure because the quantization of an embedding of the nskeleton into the (n + 1)-skeleton does not

Distinguished bases in the K-theory of multipullback quantum complex projective spaces.

We construct distinguished free generators of the $K_0$-group of the C*-algebra $C(\mathbb{CP}^n_\mathcal{T})$ of the multipullback quantum complex projective space. To this end, first we prove a

The multiplicative K-theory of compact quantum spaces

. In this paper, we refine the classification of compact quantum spaces by K-theory type initiated in [8]. We do it by introducing a multiplicative K-theory functor for unital C*-algebras taking values

Noncommutative Borsuk–Ulam-type conjectures revisited

Let $H$ be the C*-algebra of a non-trivial compact quantum group acting freely on a unital C*-algebra $A$. It was recently conjectured that there does not exist an equivariant $*$-homomorphism from
