Die Bedeutung der strategischen Planung nimmt in dem Masse zu, wie Unternehmen sich durch Fusionen, Zu- und Verkaufe verandern und das Geschaft komplexer wird. Grossunternehmen und Konzerne, zunehmend aber auch Mittelstandler, haben heute zwischen 30 und 150 selbststandige, eigenverantwortliche Geschaftseinheiten (in zahlreichen Regionen und Landern), wobei nicht selten so heterogene Sparten wie Kernkraft und Mobilfunk unter dem Dach eines einzigen Konzerns versammelt sind. Ublicherweise entwickeln alle Geschaftseinheiten jeweils einmal jahrlich ihre eigene Strategie. Zur Losung dieser...

Introducing the representation theory of groups and finite dimensional algebras, first studying basic non-commutative ring theory, this book covers the necessary background on elementary homological algebra and representations of groups up to block theory. It further discusses vertices, defect groups, Green and Brauer correspondences and Clifford theory. Whenever possible the statements are presented in a general setting for more general algebras, such as symmetric finite dimensional algebras over a field.

Then, abelian and derived categories are introduced in detail and are used to...
