For H an infinite dimensional co-Frobenius Hopf algebra over a field k, and A an H-comodule algebra, the smash product Aΰ »H \* r at is linked to the ring of coinvariants A c o H by a Morita context. We use the Morita setting to show that for co-Frobenius H, equivalent conditions for ArA c o H to be G

Let H be a Hopf algebra with bijective antipode over a commutative ring k. A right H-Galois extension of k is a right H-comodule algebra A such that k s A co H and a certain canonical map A m A Βͺ A m H is a bijection. We investigate Galois connections for Hopf᎐Galois extensions that can be formulate

## A is also an H-comodule algebra, where the product ) is defined by a) b s Ž . Ýa a m b . In this note, we observe that there is a map of pointed sets from the 0 1 twistings of A to the H-measurings from A co H to A and study the set of twistings that map to the trivial measuring. If ArA co H is
