Abstract: It is a question of Serre to characterize finitely presented groups that can serve as the fundamental group of a compact Kahler manifold, called the Kahler groups. Dimca, Papadima and Suciu classified the Kahler groups in the class of right-angled Artin groups in 2009. We classify the Kahler groups contained in the class of weighted right-angled Artin groups. This class of groups comes from the edge-weighted finite simple graphs and is a natural generalization of the right-angled Artin groups. The proof uses tropical geometry and BNS invariants. This talk is based on a joint work with Yuan Liu.
