A note on discrete uniform subgroups of Lie groups

Geometriae Dedicata, 1986
Let G be an n-dimensional connected Lie group with a left invariant Riemannian metric \(\rho\) on G. Let \(\| \|\) denote the norm on the Lie algebra \({\mathfrak G}\) of G corresponding to \(\rho\) and let k(\(\rho)\) denote the norm of the Lie bracket i.e. \(k(\rho)=\max \{\| [X,Y]\|:\) X,Y\(\in {\mathfrak G}\), \(\| X\| \leq 1\), \(\| Y\| \leq 1\}\).

Discreteness of lattices of closed subgroups of lie groups

Ukrainian Mathematical Journal, 1986
Let G be a locally compact group and let L(G) be the set of all closed subgroups of G. The family \(\{\) \(F\in L(G) :\) \(H\subseteq F\subseteq HU\}\) forms the base of a topology \(\tau\) on L(G) (H\(\in L(G)\), U runs over a neighbourhood base of unit of G). It is proved that the space \(L_{\tau}(G)\) is discrete iff G is a Lie group.

DISCRETE SUBGROUPS OF SOLVABLE LIE GROUPS OF TYPE $ (E)$

Mathematics of the USSR-Sbornik, 1971
Let and be simply connected Lie groups, and let be a lattice in . In the present article we investigate the question whether the homomorphism can be lifted to a homomorphism for the case that or is a Lie group of type . Incidentally we prove some of the properties of lattices in such groups.Bibliography: 13 items.

Discrete Subgroups Isomorphic to Lattices in Semisimple Lie Groups

American Journal of Mathematics, 1976
Let G be a locally compact topological group. A discrete subgroup T of G is said to be a lattice in G if the homogeneous space G/T carries a finite G invariant measure. A lattice T in G is said to be uniform if G/T is compact otherwise, it is said to be nonuniform.
