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

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
