Noncoherence of some lattices in Isom(Hn)

We prove noncoherence of certain families of lattices in the isometry group of the hyperbolic n-space for n greater than 3. For instance, every nonuniform arithmetic lattice in SO(n,1) is noncoherent, provided that n is at least 6.Comment: This is the version published by Geometry & Topology Monographs on 29 April 2008.

Lie groups and invariant theory

This volume, devoted to the 70th birthday of A. L. Onishchik, contains a collection of articles by participants in the Moscow Seminar on Lie Groups and Invariant Theory headed by E. B. Vinberg and A. L. Onishchik. The book is suitable for graduate students and researchers interested in Lie groups and related topics

Subsemigroups of Nilpotent Lie Groups

Abels H, Vinberg EB. Subsemigroups of Nilpotent Lie Groups. Journal of Lie Theory. 2020;30(1):171-178.For a closed subsemigroup S of a simply connected nilpotent Lie group G, we prove that either S is a subgroup, or there is an epimorphism f : G -> R such that f (s) >= 0 for all s is an element of S
