Seminar Algebraische Geometrie

On Monday, 22nd May

Bernd Kreussler (Limerick) will give a talk on

Zariski decomposition on rational surfaces and the algebraic dimension of certain 3-folds



Abstract:

The anti-Kodaira dimension of rational surfaces plays an essential role in the calculation of the algebraic dimension of certain simply connected compact 3-folds. A powerful tool to study the anti-Kodaira dimension of rational surfaces is the Zariski decomposition of an anti-canonical divisor on such a surface. In this talk, which reports on joint work with N. Honda, our results on the Zariski decomposition of an anti-canonical divisor on a rational surface will be explained. The main application of these results is aproof that a certain type of twistor space cannot exist.




Unless otherwise specified, talks take place in Arnimallee 3, room 119, from 16:00 - 18:00.
