Push-forward of Hopf--Galois extensions: the non central case
Giovanni Landi, Chiara Pagani
We study the push-forward of Hopf--Galois extensions as the algebraic counterpart of the pullback of principal bundles. We apply the theory of twisted tensor product algebras to en…

Francesco D'Andrea, Giovanni Landi, Chiara Pagani
We study the quantization of spaces whose K-theory in the classical limit is the ring of dual numbers . For a compact Hausdorff space we recall necessary and s…
