We prove a Σ-version of the result of Bieri, Neumann and Strebel [6] that for a finitely presented group G without free subgroups of rank 2 the set ∑1(G)c has no antipodal points. More precisely, we prove that for such a group G conv≤2(ℝ>0.∑1(G)c) ⊆ ℝ&

Lie groups as permutation groups: Ulam's problem in the nilpotent case
Ulam asked whether every connected Lie group can be represented on a countable structure. This is known in the linear case. We establish it for the first family of non-linear groups, namely in the nilpotent case.

We give necessary and sufficient conditions under which an amalgamated free product of finitely generated nilpotent groups is a Howson group (that is the intersection of any two finitely generated subgroups is finitely generated). Also we prove that if G
