Sommario/riassunto

Durch das 1985 verabschiedete Gramm-Rudman-Hollings-Gesetz wurde in den USA versucht, die hohe Neuverschuldung des Staates



abzubauen. Feste Defizitgrenzen und die Drohung gleichmäßiger proportionaler Kürzungen aller Ausgaben sollten dieses Ziel erreichen. In der Arbeit wird untersucht, wo die Unzulänglichkeiten dieses Gesetzes lagen (es wurde Ende 1990 grundlegend verändert) und weshalb es gescheitert ist, ja scheitern mußte.

Sommario/riassunto

Vector fields on manifolds play a major role in mathematics and other sciences. In particular, the Poincaré-Hopf index theorem gives rise to the theory of Chern classes, key manifold-invariants in geometry and topology. It is natural to ask what is the ‘good’ notion of the index of a vector field, and of Chern classes, if the underlying space becomes singular. The question has been explored by several authors resulting



in various answers, starting with the pioneering work of M.-H. Schwartz and R. MacPherson. We present these notions in the framework of the obstruction theory and the Chern-Weil theory. The interplay between these two methods is one of the main features of the monograph.
