In a sequel to their 2000 Taming Wild Extensions: Hopf Algebras and Local Galois Module Theory, Childs and colleagues survey the state of the art in Hopf-Galois theory and Hopf-Galois module theory. They begin with an algebraic approach, focusing...Loe edasi...
Gives two new methods for constructing p-elementary Hopf algebra orders over the valuation ring R of a local field K containing the p-adic rational numbers. This book features a method which constructs Hopf orders using isogenies of commutat...Loe edasi...

The structure theory of abelian extensions of commutativerings is a subjectwhere commutative algebra and algebraicnumber theory overlap. This exposition is aimed at readerswith some background in either of these two fields. Emphasisis given...Loe edasi...
