We compute the Chern-Weil map introduced by Hajac and Maszczyk associated with a Hopf-Galois extension in the case of $2$-cocycle deformation of the latter. We analyze the cases where the $2$-cocycle belongs to the structure Hopf algebra, an external

We study the relationship between antipodes on a Hopf algebroid $\mathcal{H}$ in the sense of B\"ohm-Szlachanyi and the group of twists that lies inside the associated convolution algebra. We specialize to the case of a faithfully flat $H$-Hopf-Galoi

We extend twisted inner fluctuations to twisted spectral triples that do not meet the twisted first-order condition, following what has been done in [6] for the non-twisted case. We find a similar non-linear term in the fluctuation, and work out the
