Abstract: We investigate the relations between the cut number, and the first Betti number, of manifolds We prove that the cut number of a ``generic'' manifold is at most This is a rather unexpected result since specific examples of manifolds with large and are hard to construct. We also prove that for any complex semisimple Lie algebra there exists a manifold with and Such manifolds can be explicitly constructed.
