Infinite generation of non-cocompact lattices on right-angled buildings

چکیده
Tree lattices have been well-studied (see [BL]). Less understood are lattices on higherdimensional CAT(0) complexes. In this paper, we consider lattices on X a locally finite, regular right-angled building (see Davis [D] and Section 1 below). Examples of such X include products of locally finite regular or biregular trees, or Bourdon’s building Ip,q [B], which has apartments hyperbolic planes tesselated by right-angled p–gons and all vertex links the complete bipartite graph Kq,q .

Lattices Acting on Right-angled Hyperbolic Buildings
Let X be a right-angled hyperbolic building. We show that the lattices in Aut(X) share many properties with tree lattices. For example, we characterise the set of covolumes of uniform and of nonuniform lattices in Aut(X), and show that the group Aut(X) admits an infinite ascending tower of uniform and of nonuniform lattices. These results are proved by constructing a functor from graphs of grou...

متن کاملHyperbolic Triangular Buildings Without Periodic Planes of Genus 2
We study surface subgroups of groups acting simply transitively on vertex sets of certain hyperbolic triangular buildings. The study is motivated by Gromov’s famous surface subgroup question: Does every oneended hyperbolic group contain a subgroup which is isomorphic to the fundamental group of a closed surface of genus at least 2? In [10] and [3] the authors constructed and classified all grou...
متن کاملUniform Lattices Acting on Some Hyperbolic Buildings
Let X be a 2-dimensional right-angled hyperbolic building. We characterise the set of covolumes of uniform lattices in Aut(X). We also show that the group Aut(X) admits an infinite ascending tower of uniform lattices.
متن کاملCounting Overlattices for Polyhedral Complexes
We investigate the asymptotics of the number of “overlattices” of a cocompact lattice Γ in Aut(X), where X is a locally finite polyhedral complex. We use complexes of groups to prove an upper bound for general X, and a lower bound for certain right-angled buildings.
