Some questions about the dimension of a group action

Some questions about the dimension of a group action This article discusses three families of groups: Z ≀ Zn, PL(In), and PL(Sn) (the last two being the families of groups of piecewise‐linear homeomorphisms of standard n‐dimensional spaces). It is shown that for positive n ∈ N, Z ≀ Zn embeds in PL(In), which embeds in PL(Sn). It is known that Z ≀ Z2 fails to embed in PL(I1), and this article extends that previous result to show that Z ≀ Z2 also fails to embed in PL(S1). The nature of the proofs of these embedding and non‐embedding results hints that there may be corresponding non‐embedding results in higher dimensions. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Bulletin of the London Mathematical Society Wiley

Abstract

This article discusses three families of groups: Z ≀ Zn, PL(In), and PL(Sn) (the last two being the families of groups of piecewise‐linear homeomorphisms of standard n‐dimensional spaces). It is shown that for positive n ∈ N, Z ≀ Zn embeds in PL(In), which embeds in PL(Sn). It is known that Z ≀ Z2 fails to embed in PL(I1), and this article extends that previous result to show that Z ≀ Z2 also fails to embed in PL(S1). The nature of the proofs of these embedding and non‐embedding results hints that there may be corresponding non‐embedding results in higher dimensions.
