New Directions in Hopf Algebras
by S. Montgomery, H. Schneider
Publisher: Cambridge University Press 2002
Number of pages: 485
Hopf algebras have important connections to quantum theory, Lie algebras, knot and braid theory, operator algebras, and other areas of physics and mathematics. The book gives a clear picture of the current trends in this active field, with a focus on what is likely to be important in future research.

This book presents the basic theory of commutators in congruence modular varieties and some of its strongest applications. The authors take an algebraic approach, using some of the shortcuts that Taylor and others have discovered.
