We announce results about the structure and arithmeticity of all possible lattice embeddings of a class of countable groups which encompasses all linear groups with simple Zariski closure, all groups with non-vanishing first l2-Betti number, word hyperbolic groups, and, more general, convergence groups. 

An adelic arithmeticity theorem for lattices in products

In this paper we prove that, under mild assumptions, a lattice in a product of semi-simple Lie group and a totally disconnected locally compact group is, in a certain sense, arithmetic. We do not

Non-discrete simple locally compact groups

Simple Lie groups and simple algebraic groups over local fields are the most prominent members of the class S of compactly generated non-discrete simple locally compact groups. We outline a new

Model geometries of finitely generated groups

. We study model geometries of finitely generated groups. If a finitely generated group does not contain a non-trivial finite rank free abelian commensurated subgroup, we show any model geometry is

Local-to-Global-rigidity of lattices in SL n ( 𝕂 )

A vertex-transitive graph 𝒢 is called Local-to-Global rigid if there exists R > 0 such that every other graph whose balls of radius R are isometric to the balls of radius R in 𝒢 is covered by 𝒢 .

Measure equivalence classification of transvection-free right-angled Artin groups

We prove that if two transvection-free right-angled Artin groups are measure equivalent, then they have isomorphic extension graphs. As a consequence, two right-angled Artin groups with finite outer

Amenable uniformly recurrent subgroups and lattice embeddings

We study lattice embeddings for the class of countable groups $\unicode[STIX]{x1D6E4}$ defined by the property that the largest amenable uniformly recurrent subgroup

Local-to-Global-rigidity of graphs quasi-isometric to the Bruhat-Tits building of $PSL_n(\mathbb{Q}_p)$

A vertex-transitive graph $\mathcal{G}$ is called Local-to-Global rigid if there exists $R>0$ such that every other graph whose balls of radius $R$ are isometric to the balls of radius $R$ in

Bounded cohomology of subgroups of mapping class groups (Hyperbolic Spaces and Discrete Groups)

We show that every subgroup of the mapping class group MCG(S )o f ac ompact surface S is either virtually abelian or it has innite dimensional second bounded cohomology. As an application, we give

A topological Tits alternative

Let k be a local eld, and GLn(k) a linear group over k. We prove that either contains a relatively open solvable subgroup, or it contains a relatively dense free subgroup. This result has

Quasi-isometries of rank one S-arithmetic lattices

We complete the quasi-isometric classification of irreducible lattices in semisimple Lie groups over nondiscrete locally compact fields of characteristic zero by showing that any quasi-isometry of a

Quasi-isometric rigidity of higher rank S -arithmetic lattices

We show that S-arithmetic lattices in semisimple Lie groups with no rank one factors are quasi-isometrically rigid.

Measure equivalence rigidity of the mapping class group

We show that the mapping class group of a compact orientable surface with higher complexity satisfies the following rigidity in the sense of measure equivalence: If the mapping class group is measure

Weak Notions of Normality and Vanishing up to Rank in L2-Cohomology

We study vanishing results for L 2 -cohomology of countable groups under the presence of subgroups that satisfy some weak normality condition. As a consequence we show that the L 2 -Betti numbers of

Non-discrete simple locally compact groups

Simple Lie groups and simple algebraic groups over local fields are the most prominent members of the class S of compactly generated non-discrete simple locally compact groups. We outline a new

Vanishing of $\ell ^2$-Betti numbers of locally compact groups as an invariant of coarse equivalence

We provide a short proof that the vanishing of $\ell^2$-Betti numbers of unimodular locally compact second countable groups is an invariant of coarse equivalence.
