The BNS invariants of the generalized solvable Baumslag-Solitar groups and of their finite index subgroups

Wagner Sgobbi, Peter Wong

We compute the Bieri-Neumann-Strebel invariants $Σ^{1}$ for the generalized solvable Baumslag-Solitar groups $Γ_{n}$ and their finite index subgroups. Using $Σ^{1}$ , we show that certain…

Twisted conjugacy in fundamental groups of geometric $3$ -manifolds

Daciberg Gonçalves, Parameswaran Sankaran, Peter Wong

A group $G$ has property $R_{\infty}$ if for every $ϕ \in A u t (G)$ , there are an infinite number of $ϕ$ -twisted conjugacy classes of elements in $G$ . In this note, we determine the $R_…

Computation of Nielsen and Reidemeister coincidence numbers for multiple maps

Thaís F. M. Monis, Peter Wong

Let $f_{1}, ..., f_{k} : M \to N$ be maps between closed manifolds, $N (f_{1}, ..., f_{k})$ and $R (f_{1}, ..., f_{k})$ be the Nielsen and the Reideimeister coincidence numbers respectively. In this note…

Twisted conjugacy in free products

Daciberg Goncalves, Parameswaran Sankaran, Peter Wong

Let $ϕ : G \to G$ be an automorphism of a group which is a free-product of finitely many groups each of which is freely indecomposable and two of the factors contain proper finite ind…

Twisted conjugacy and commensurability invariance

Parameswaran Sankaran, Peter Wong

A group $G$ is said to have property $R_{\infty}$ if for every automorphism $φ \in Aut (G)$ , the cardinality of the set of $φ$ -twisted conjugacy classes is infinite. Many class…

Exponents of $[Ω (S^{r + 1}), Ω (Y)]$

Marek Golasiński, Daciberg Lima Gonçalves, Peter Wong

We investigate the exponents of the total Cohen groups $[Ω (S^{r + 1}), Ω (Y)]$ for any $r \geq 1$ . In particular, we show that for $p \geq 3$ , the $p$ -primary exponents of $[Ω(\ma…
