On Modules Associated to Coalgebra Galois Extensions

open access: yesJournal of Algebra, 1999
For a given entwining structure $(A,C)_ $ involving an algebra $A$, a coalgebra $C$, and an entwining map $ : C\otimes A\to A\otimes C$, a category $\M_A^C( )$ of right $(A,C)_ $-modules is defined and its structure analysed. In particular, the notion of a measuring of $(A,C)_ $ to $(\tA,\tC)_\tpsi$ is introduced, and certain functors between ...
