✦ Synopsis

We show that the isomorphism ΞΆ B/A B/A β†’ A B introduced by the second author for a subintegral extension A βŠ† B of positively graded rings with A 0 = B 0 is also an isomorphism if A βŠ† B is only a weakly subintegral extension.

Let S = k x 1 x n be a polynomial ring, and let Ο‰ S be its canonical module. First, we will define squarefreeness for n -graded S-modules. A Stanley-Reisner ring k = S/I , its syzygy module Syz i k , and Ext i S k Ο‰ S are always squarefree. This notion will simplify some standard arguments in the S

Let A be an algebra over a commutative ring R. If R is noetherian and A β€’ is pure in R A , then the categories of rational left A-modules and right A β€’ -comodules are isomorphic. In the Hopf algebra case, we can also strengthen the Blattner-Montgomery duality theorem. Finally, we give sufficient con
