This book studies Hopf algebras over valuation rings of local fields and their application to the theory of wildly ramified extensions of local fields. The resu
Hopf algebras have been shown to play a natural role in studying questions of integral module structure in extensions of local or global fields. This book surve
"This remarkable reference covers topics such as quantum groups, Hopf Galois theory, actions and coactions of Hopf algebras, smash and crossed products, and the
