✦ Synopsis

A Galois correspondence is exhibited between right coideals subalgebras of a finite-dimensional pointed Hopf algebra acting homogeneously and faithfully on a free associative algebra and free subalgebras containing the invariants of this action.

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 ª A m H is a bijection. We investigate Galois connections for Hopf᎐Galois extensions that can be formulate

For H an infinite dimensional co-Frobenius Hopf algebra over a field k, and A an H-comodule algebra, the smash product A࠻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 B࠻ H be a crossed product algebra over an algebraically closed field, with H a finite dimensional Hopf algebra. We give an explicit equivalence between the category of finite dimensional B࠻ H-modules whose restriction to B is a direct sum of copies of a stable irreducible B-module, and the categ
