C. Berger,J. Böckenförde,A. Müggethat the reader is more or less familiar with elementary notions of linear algebra. In the beginning sections we collect fundamental results on linear algebra, mostly without proof, for the convenience of later reference. The notions related to normed vector spaces and analysis with vectors and oper

Angewandte Elektrische Meßtechnikvectors (or eigenprojections) change with the operator, in particular when the operator depends on a parameter analytically. This is a special case of a more general and more interesting problem in which the operator acts in an infinite-dimensional space.

Operator theory in finite-dimensional vector spaces, hat, sondern die gemeinsamen Fundamente. Da ich die Programmatik einer allgemeinen erziehungswissenschaftlichen Biographieforschung mit einem bildungstheoretischen Zuschnitt an verschiedenen Stellen ausgeführt habe (Marotzki 1990, 1991a-c, 1996), erinnere ich hier nur kursorisch daran, dass es sich
