Which 3-manifold groups are Kähler groups?Alexandru Dimca and Alexander I. Suciu (1) Université de Nice Sophia Antipolis, France

The question in the title, first raised by Goldman and Donaldson, was partially answered by Reznikov. We give a complete answer, as follows: if G can be realized as both the fundamental group of a closed 3-manifold and of a compact Kähler manifold, then G must be finite—and thus belongs to the well-known list of finite subgroups of O(4), acting freely on S3.
Keywords: Kähler manifold, 3-manifold, fundamental group, cohomology ring, resonance variety, isotropic subspace
