We work with a conjecture on the BNS-invariant of Artin groups stated by Almeida and Kochloukova. We show that the class of Artin groups that satisfy this conjecture is closed under finite graph products. As a consequence, we show that the conjecture

We find a condition on the underlying graph of an Artin group that fully determines if it is subgroup separable. As a consequence, an Artin group is subgroup separable if and only if it can be obtained from Artin groups of ranks at most 2 via a finit

The BNS-invariant or Σ 1 {\Sigma^{1}} -invariant is the first of a series of geometric invariants of finitely generated groups defined in the eighties that are deeply related to finiteness properties of their subgroups, although they are very hard t

We classify the Bieri–Neumann–Strebel invariant Σ 1 ( G ) {\Sigma^{1}(G)} for a class of Artin groups with minimal graphs of arbitrary circuit rank.

We define an Artin group of circuit rank 1 as an Artin group based on a connected graph with fundamental group a free group of rank 1. For an Artin group G of circuit rank 1 the Bieri–Neumann–Renz–Strebel invariant Σ 1 ( G , ℤ ) ${\Sigma ^1(
