Cancellation properties of exotic 4-dimensional positive scalar curvature metrics
Johannes Ebert (Münster)
The spectrum of the Dirac operator on spherical space forms is calculated. Manifolds with many Killing spinors are characterized. In the last section non-isometric space forms with the same Dirac spectrum are constructed.
