Weak potency of fundamental groups of graphs of groups.
Weighted -cohomology of Coxeter groups based on barycentric subdivisons.

When is Zn the only Group of Order n?
Which 3-manifold groups are Kähler groups?
The question in the title, first raised by Goldman and Donaldson, was partially answered by Reznikov. We give a complete answer, as follows: if can be realized as both the fundamental group of a closed 3-manifold and of a compact Kähler manifold, then must be finite—and thus belongs to the well-known list of finite subgroups of , acting freely on .
Wielandt series and defects of subnormal subgroups in finite soluble groups
Word distance on the discrete Heisenberg group
We establish an exact formula for the word distance on the discrete Heisenberg group ℍ₃ with its standard set of generators. This formula is then used to prove the almost connectedness of the spheres for this distance.
Words with intervening neighbours in infinite Coxeter groups are reduced.
W-perfect groups
In the present article we define W-paths of elements in a W-perfect group as a useful tools and obtain their basic properties.
