On fundamental groups of complex hyperbolic surfaces
by
Michael Kapovich
University of Utah

We show that the fundamental group of a compact complex-hyperbolic surface M cannot fit into a short exact sequence
1 --> \pi1(S1) --> \pi1(M) --> \pi1(S2) --> 1
where S1, S2 are hyperbolic Riemann surfaces. As an application of the technique used in the proof we show that there are compact complex-hyperbolic surfaces whose fundamental groups are not coherent.
