A structure theorem and left-orderability of a quotient of quasi-isometry group of the real line

Swarup Bhowmik, Prateep Chakraborty

It is well-known that $Q I (R) ≅ (Q I (R_{+}) \times Q I (R_{-})) ⋊ < t >$ , where $Q I (R)$ (resp. $Q I (R_{+}) (≅ Q I (R_{-}))$ ) is t…

A Combinatorial Criterion and Center for the quasi-isometry groups of Euclidean spaces

Swarup Bhowmik, Prateep Chakraborty

In this study, we introduce the notion of $P L_{δ}$ -homeomorphisms of $R^{n}$ . Furthermore, we provide a combinatorial criterion reliant on the vertices and edges of simplicial…

On the center of the group of quasi-isometries of the real line

Prateep Chakraborty

Let $Q I (R)$ denote the group of all quasi-isometries $f : R \to R .$ Let $Q_{+} (and Q_{-})$ denote the subgroup of $Q I (R)$ consisting of elemen…
