Abstract

The second Betti number of a smooth, closed, connected and simply connected, four-dimensional spin manifold is greater or equal 11/8 times the abolute value of its signature.

This paper has been withdrawn by the author. Proposition 5.2 is wrong. The author is grateful to Tom Mrowka for pointing out the mistake
