ON THE GROUPS OF THE INFINITELY GENERATED FREE ABELIAN GROUPS AUTOMORPHISMS
Let A be an infinitely generated free abelian group. The paper shows that all automorphisms of the group Aut(A) are inner.

The fundamental group and Galois coverings of hexagonal systems in 3-space
We consider hexagonal systems embedded into the 3-dimensional space ℝ3. We define the fundamental group π1(G) of such a system G and show that in case G is a finite hexagonal system with boundary, then π1(G) is a (non-Abelian) free group.

The Magnus representation and homology cobordism groups of homology cylinders
A homology cylinder over a compact manifold is a homology cobordism between two copies of the manifold together with a boundary parametrization. We study abelian quotients of the homology cobordism group of homology cylinders. For homology cylinders over
