Bieri-Neumann-Strebel-Renz invariants and tropical varieties of integral homology jump loci
Yongqiang Liu, Yuan Liu
Papadima and Suciu studied the relationship between the Bieri-Neumann-Strebel-Renz (short as BNSR) invariants of spaces and the homology jump loci of rank one local systems. Recent…

The applications of Bieri-Neumann-Strebel invariant on Kähler groups
Yuan Liu
We give several applications of the Bieri-Neumann-Strebel invariant on Kähler groups. Specifically, we provide simpler proof of the Napier-Ramachandran theorem on the HNN extension…
