Zusammenfassung
In this Diplomarbeit we show that, when parametrized by their rational cohomology type, "most" compact, simply-connected 8-dimensional manifolds (with possibly one singular point) have only trivial S1-symmetry. To obtain restrictions on the rational cohomology type in the case of a non-trivial S1-action, we study the minimal Hirsch-Brown model of the S1-equivariant cohomology, and derive relations between the cohomology type and the rational cohomology of the fixed point set. Some of the results obtained are interesting in their own right: We show that for a "generic" compact, simply-connected, even-dimensional Q-Poincaré duality space X with S1-action the fixed point set has at most one component of high formal dimension;
