Buch. Zustand: Neu. Neuware -Matroid theory was invented in the middle of the 1930s by two mathematicians independently, namely, Hassler Whitney in the USA and Takeo Nakasawa in Japan. Whitney became famous, but Nakasawa remained anonymous until two decades ago. He left only four papers to the mathematical community, all of them written in the middle of the 1930s. It was a bad time to have lived in a country that had become as eccentric as possible. Just as Nazism became more and more flamboyant in Europe in the 1930s, Japan became more and more esoteric and fanatical in the same time period. This book explains the little that is known about Nakasawäs personal life in a Japan that had, among other failures, lost control over its military. This book contains his four papers in German and their English translations as well as some extended commentary on the history of Japan during those years. The book also contains 14 photos of him or his family. Although the veil of mystery surrounding Nakasawäs life hasonly been partially lifted, the work presented in this book speaks eloquently of a tragic loss to the mathematical community.Springer Basel AG in Springer Science + Business Media, Heidelberger Platz 3, 14197 Berlin 248 pp. Englisch.

Buch. Zustand: Neu. Neuware -This volume contains some papers written by the participants to the Session ¿Quaternionic and Cli ord Analysis¿ of the 6th ISAAC Conference (held in Ankara, Turkey, in August 2007) and some invited contributions. The contents cover several di erent aspects of the hypercomplex analysis. All contributed - pers represent the most recent achievements in the area as well as ¿state-of-the art¿ expositions. The Editors are grateful to the contributors to this volume, as their works show how the topic of hypercomplex analysis is lively and fertile, and to the r- erees, for their painstaking and careful work. The Editors also thank professor M.W. Wong, President of the ISAAC, for his support which made this volume possible.
