The applications of Bieri–Neumann–Strebel invariant on Kähler groups
We give several applications of the Bieri–Neumann–Strebel invariant on Kähler groups. Specifically, we provide a simpler proof of the Napier–Ramachandran theorem on the HNN decomposition of Kähler groups and show that amenable Kähler groups have an empty complement of the BNS invariant.
