Hopf algebras have important connections to quantum theory, Lie algebras, knot and braid theory, operator algebras and other areas of physics and mathematics. They have been intensely studied in the past; in particular, the solution of a number of conjectures of Kaplansky from the 1970s has led to progress on the classification of semisimple Hopf algebras and on the structure of pointed Hopf algebras. Among the topics covered are results toward the classification of finite-dimensional Hopf algebras (semisimple and non-semisimple), as well as what is known about the extension theory of Hopf algebras. Some papers consider Hopf versions of classical topics, such as the Brauer group, while others are closer to work in quantum groups. The book also explores the connections and applications of Hopf algebras to other fields.

An international perspective on the latest research in polymer solar cell technology.
The Gunpowder Epic is one of three planned publications on military technology within Dr Needham's immense undertaking. The discovery of gunpowder in China by the 9th century AD was followed by its rapid applications. It is now clear that the whole development from bombs and grenades to the invention of the metal-barrel hand gun took place in the Chinese culture area before Europeans had any knowledge of the mixture itself. Uses in civil engineering and mechanical engineering were equally important, before the knowledge of gunpowder spread to Europe in the thirteenth and fourteenth centuries. Dr Needham's new work continues to demonstrate the major importance of Chinese science and technology to world history and maintains the tradition of one of the great scholarly works of the twentieth century.
