Query: Gysin exact sequences for quantum weighted lens spaces   We describe quantum weighted lens spaces as total spaces of quantum principal
circle bundles, using a Cuntz-Pimsner model. The corresponding Pimsner exact
sequence is interpreted as a noncommutative analogue of the Gysin exact
sequence. We use the sequence to compute the K-theory and K-homology groups of
quantum weighted lens spaces, extending previous results and computations due
to the author and collaborators.
