Abstract

We construct examples of $CAT (0)$ , free-by-cyclic, hyperbolic groups which fiber in infinitely many ways over $ℤ$ . The construction involves adding a specialized square 2–cell to a non-positively curved, squared 2–complex defined by labeled oriented graphs. The fundamental groups of the resulting complexes are $CAT (0)$ , hyperbolic, free-by-cyclic and can be mapped onto $ℤ$ in infinitely many ways.
