Comportement harmonique des densités conformes et frontière de Martin

Thomas Roblin (2011)

Bulletin de la Société Mathématique de France

Traitant la série de Poincaré d’un groupe discret d’isométries en courbure négative comme un noyau de Green, on établit une théorie du potentiel assez comparable à la théorie classique pour affirmer un parallèle entre densités conformes à la Patterson-Sullivan et densités harmoniques, et notamment définir une frontière de Martin où les densités ergodiques forment la partie minimale, et enfin l’identifier géométriquement sous hypothèse d’hyperbolicité.

Continued fractions on the Heisenberg group

Anton Lukyanenko, Joseph Vandehey (2015)

Acta Arithmetica

We provide a generalization of continued fractions to the Heisenberg group. We prove an explicit estimate on the rate of convergence of the infinite continued fraction and several surprising analogs of classical formulas about continued fractions.

Counting arithmetic subgroups and subgroup growth of virtually free groups

Amichai Eisenmann (2015)

Journal of the European Mathematical Society

Let $K$ be a $p$ -adic field, and let $H = P S L_{2} (K)$ endowed with the Haar measure determined by giving a maximal compact subgroup measure $1$ . Let $A L_{H} (x)$ denote the number of conjugacy classes of arithmetic lattices in $H$ with co-volume bounded by $x$ . We show that under the assumption that $K$ does not contain the element $ζ + ζ^{- 1}$ , where $ζ$ denotes the $p$ -th root of unity over $ℚ_{p}$ , we have $lim_{x \to \infty} \frac{log A L_{H} (x)}{x log x} = q - 1$ where $q$ denotes the order of the residue field of $K$ .

Designs, groups and lattices

Christine Bachoc (2005)

Journal de Théorie des Nombres de Bordeaux

The notion of designs in Grassmannian spaces was introduced by the author and R. Coulangeon, G. Nebe, in [3]. After having recalled some basic properties of these objects and the connections with the theory of lattices, we prove that the sequence of Barnes-Wall lattices hold $6$ -Grassmannian designs. We also discuss the connections between the notion of Grassmannian design and the notion of design associated with the symmetric space of the totally isotropic subspaces in a binary quadratic space, which...
