Entwined structures A, C, were introduced by Brzezinski and Majid to study the interdependence of an R-algebra A and an R-coalgebra C, R a commutative ring. It turned out that this relationship can also be expressed by the fact that A m C has a canonical A-coring structure. More generally, weak entw
