The Serre spectral sequence of a noncommutative fibration for de Rham cohomology

EJ Beggs, Tomasz Brzezinski

For differential calculi on noncommutative algebras, we construct a twisted de Rham cohomology using flat connections on modules. This has properties similar, in some respects, to…

The structure of weak coalgebra-Galois extensions

Tomasz Brzezinski, Ryan B. Turner, Adam P. Wrightson

Weak coalgebra-Galois extensions are studied. A notion of an invertible weak entwining structure is introduced. It is proven that, within an invertible weak entwining structure, th…
