Abstract |
|
|
| The nontrivial component of the intersection form of nonsmooth four-manifolds is proportional to the Cartan matrix of
E8. Since the background geometry of all elementary particle field theories is a smooth four-manifold, this intersection form will be
introduced through the embedding of an infinite-genus surface with a nonsmooth structure in the neighbourhood of the ideal boundary. |
