New simple lattices in products of trees and their projections
Nicolas Radu
Let be a group acting freely and transitively on the product of two regular trees of degree and . We develop a…
A homogeneous -building with a non-discrete automorphism group is Bruhat-Tits
Nicolas Radu
Let be a locally finite thick building of type . We show that, if the type-preserving automorphism group of is transitive on panels of each…
Chabauty limits of simple groups acting on trees
Pierre-Emmanuel Caprace, Nicolas Radu
Let be a locally finite tree without vertices of degree . We show that among the closed subgroups of acting with a bounded number of orbits, the Chabauty-c…
A lattice in a residually non-Desarguesian -building
Nicolas Radu
We build a building of type and a discrete group of automorphisms acting simply transitively on its set of vertices. The characteristic feature of this building is tha…
A classification theorem for boundary 2-transitive automorphism groups of trees
Nicolas Radu
Let be a locally finite tree all of whose vertices have valency at least . We classify, up to isomorphism, the closed subgroups of acting -transitively…
