A Simple Proof of a Theorem of Whyte
Kevin Whyte showed that all Baumslag–Solitar groups BS(p,q) with 1 < p < q are quasi-isometric [Whyte, K., Geom. Funct. Anal. 11 (2001), 1327–1343]. We provide an elementary geometric proof.

Quasi-actions on trees I. Bounded valence
Given a bounded valence, bushy tree T, we prove that any cobounded quasi-action of a group G on T is quasiconjugate to an action of G on another bounded valence, bushy tree T'. This theorem has many
Quasi-isometric rigidity for the solvable Baumslag-Solitar groups, II
Let BS(1,n)= . We prove that any finitely-generated group quasi-isometric to BS(1,n) is (up to finite groups) isomorphic to BS(1,n). We also show that any uniform group of quasisimilarities of the
Lipschitz Equivalence Class, Ideal Class and the Gauss Class Number Problem
In this paper, we study the question of classifying self-similar sets under bi-Lipschitz mappings and obtain an important bi-Lipschitz invariant, which is an ideal of a ring related to IFS. Roughly
Problems on the geometry of finitely generated solvable groups
A survey of problems, conjectures, and theorems about quasi-isometric classification and rigidity for finitely generated solvable groups.
Morse quasiflats I
TLDR
This paper introduces a number of alternative definitions of Morse quasiflats, and under appropriate assumptions on the ambient space it is shown that they are equivalent and quasi-isometry invariant; it also gives a variety of examples.
Quasi-isometric rigidity for graphs of virtually free groups with two-ended edge groups
Abstract We study the quasi-isometric rigidity of a large family of finitely generated groups that split as graphs of groups with virtually free vertex groups and two-ended edge groups. Let G be a
Twisted conjugacy and commensurability invariance
Abstract A group 𝐺 is said to have property R ∞ R_{\infty} if, for every automorphism φ ∈ Aut ⁢ ( G ) \varphi\in\mathrm{Aut}(G) , the cardinality of the set of 𝜑-twisted conjugacy classes is
The geometry of groups containing almost normal subgroups
A subgroup $H\leq G$ is said to be almost normal if every conjugate of $H$ is commensurable to $H$. If $H$ is almost normal, there is a well-defined quotient space $G/H$. We show that if a group $G$
