| Abstract: | 4-dimensional manifolds exhibit phenomena which do not happen in any other dimension: there are examples of infinitely many smooth 4-manifolds which are homeomorphic but not diffeomorphic.
The ’exotic’ behaviour of a smooth 4-manifold seems to be very closely related to the genera of 2-dimensional surfaces it contains. We will discuss a method for changing the differentiable structure of the famous K3-surface. |
