Some New CAT(0) Free-by-Cyclic Groups
نویسندگان
چکیده
We show the existence of several new infinite families polynomially-growing automorphisms free groups whose mapping tori are CAT(0) free-by-cyclic groups. Such thick, and thus not relatively hyperbolic. These first comprising infinitely many examples for each rank nonabelian group; they contrast strongly with Gersten’s example a thick group which cannot be subgroup group.

POS-groups with some cyclic Sylow subgroups
A finite group G is said to be a POS-group if for each x in G the cardinality of the set {y in G | o(y) = o(x)} is a divisor of the order of G. In this paper we study the structure of POS-groups with some cyclic Sylow subgroups.
متن کامل`2–torsion of Free-by-cyclic Groups
We provide an upper bound on the `2–torsion of a free-bycyclic group, −ρ(2)(F oΦ Z), in terms of a relative train-track representative for Φ ∈ Aut(F). Our result shares features with a theorem of Lück–Schick computing the `2–torsion of the fundamental group of a 3–manifold that bers over the circle in that it shows that the `2–torsion is determined by the exponential dynamics of the monodromy. ...
متن کاملDynamics on Free-by-cyclic Groups
Given a free-by-cyclie group G = FN oφ Z determined by a hyperbolic and fully irreducible outer automorphism φ ∈ Out(FN ), with u0 : G → Z the homomorphism having ker(u0) = FN , we construct a K(G, 1) 2–complex X called the folded mapping torus of φ, and equip it with a semiflow. We show that X enjoys many similar properties to those proven by Thurston and Fried for the mapping torus of a pseud...
متن کاملFree-by-cyclic Groups Have Solvable Conjugacy Problem
We show that the conjugacy problem is solvable in [finitely generated free]-by-cyclic groups, by using a result of O. Maslakova that one can algorithmically find generating sets for the fixed subgroups of free group automorphisms, and one of P. Brinkmann that one can determine whether two cyclic words in a free group are mapped to each other by some power of a given automorphism. We also solve ...
متن کاملMcmullen Polynomials and Lipschitz Flows for Free-by-cyclic Groups
Consider a group G and an epimorphism u0 : G → Z inducing a splitting of G as a semidirect product ker(u0)oφ Z with ker(u0) a finitely generated free group and φ ∈ Out(ker(u0)) representable by an expanding irreducible train track map. Building on our earlier work [DKL], in which we realized G as π1(X) for an Eilenberg-Maclane 2–complex X equipped with a semiflow ψ, and inspired by McMullen’s T...
