Seminarraum IGT, Raum 7.530, Pfaffenwaldring 57 Abstract:

We demonstrate how intersection theory can be used to cal- culate the cohomology of G2-manifolds obtained by the gener- alized Kummer construction. For one example we find the ge- nerators of the rational cohomology ring and describe the product structure.
