Gorbatsevich, V. V. On Lie groups with lattices and their properties. (English. Russian original) Zbl 0619.22014 Sov. Math., Dokl. 33, 321-325 (1986); translation from Dokl. Akad. Nauk SSSR 287, 33-37 (1986). Some results about lattices in Lie groups are announced. (As usual, by a lattice \(\Gamma\) in a Lie group G we mean a discrete subgroup such that the volume of the quotient space G/\(\Gamma\) is finite.) The main result is the following Theorem 1. The set of all connected Lie groups, considered up to isomorphism and containing uniform lattices, is countable. (The lattice \(\Gamma\) in G is called uniform if the space G/\(\Gamma\) is compact.) Let us mention two other results announced in the paper: Theorem 2. The number of connected semisimple Lie groups G (considered up to isomorphism) without compact factors containing uniform lattices isomorphic to a given group is always finite. Theorem 9. Let M be a compact homogeneous manifold. Then Novikov’s conjecture on the homotopy invariance of higher signatures is valid for its fundamental group \(\pi_ 1(M).\) It is written in the paper that theorem 9 is an application of the results about lattices in Lie groups.
