If H is cocommutative, then it is known that all commutative H-module algebras are integral over its invariants. Here we prove this result for those Hopf algebras H such that either H is involutionary with Char K Β¦ dim H or H has a cocommutative coradical and K is of positive characteristic. Example

We investigate certain pure injective modules over generalised Weyl algebras. We consider pure injective hulls of finite length modules, the elementary duals of these, torsionfree pure injective modules, and the closure in the Ziegler spectrum of the category of finite length modules supported on a
For every natural number m, there exists a noncommutative valuation ring R with a completely prime ideal P so that there are exactly m nonisomorphic indecomposable injective right R-modules with P as associated prime ideal.
