Fixed points of finite groups acting on generalised Thompson groups
No full textWe study centralisers of finite order automorphisms of the generalised Thompson groups Fn, ? and conjugacy classes of finite sub- groups in finite extensions of Fn, ?. In particular we show that centralisers of finite automorphisms in Fn, ? are either of type FP? or not finitely generated. As an application we deduce the following result about the Bredon type of such finite extensions: any finite extension of Fn, ?, where the elements of finite order act on Fn, ? via conjugation with piecewise-linear homeomorphisms, is of type Bredon F?. In particular finite extensions of F = F2,? are of type Bredon F?
On the Alexander theorem for the oriented Thompson group \overarrow F
No full textIn [10] and [12] Vaughan Jones introduced a construction which yields oriented knots and links from elements of the oriented Thompson group F. In this paper we prove, by analogy with Alexander’s classical theorem establishing that every knot or link can be represented as a closed braid, that given an oriented knot /link L, there exists an element g in F whose closure L(g) is L

The action of the Thompson group F on infinite trees
No full textWe construct an action of the Thompson group F on a compact space built from pairs of infinite, binary rooted trees. The action arises as an F-equivariant compactification of the action of F by translations on one of its homogeneous spaces, F/H_2, corresponding to a certain subgroup H_2 of F. The representation of F on the Hilbert space l^2(F/H_2) is faithful on the complex group algebra C[F]
Sous-facteurs de L(F∞) d'indice 4cos2π/n,n≥3
No full textLet Q be a factor of type II1, λ a number in the Jones discrete series {4cosπ/m:m≥3}, and {ei} the Jones projections associated with λ. Denote by A2n and A1n the finite-dimensional von Neumann algebras generated, respectively, by {1,e2,⋯,en} and {1,e1,⋯,en}, with the corresponding traces. The author shows that, for n sufficiently large, the index of the inclusion An=(Q⊗A2n)∗A2nA1n⊂(Q⊗A2n+1)∗A2n+1A1n+1=An+1 is equal to λ (here ∗ denotes the reduced, amalgamated free product of the algebras in question). Using the random matrix model of Voiculescu, he proves that if Q is the von Neumann algebra L(F∞) of the free group with infinitely many generators, then An is isomorphic to L(F∞).
The two facts together imply the existence, for any λ in the Jones discrete series, of an irreducible subfactor of L(F∞) of index λ. This constitutes the first example of a nonhyperfinite, non-Γ II1 factor such that its Jones invariant is fully computable (the existence of nonirreducible subfactors of L(F∞) for any index ≥4 is a simple consequence of known results)
TWISTED CONJUGACY CLASSES IN R. THOMPSON`S GROUP F
No full textIn this article, we prove that any automorphism of R. Thompson`s group F has infinitely many twisted conjugacy classes. The result follows from the work of Brin, together with standard facts about R. Thompson`s group F, and elementary properties of the Reidemeister numbers
