Obstructions for deformations of complexes
We develop two approaches to obstruction theory for deformations of derived isomorphism classes of complexes of modules for a profinite group over a complete local Noetherian ring of positive residue characteristic.

On - and -decomposable finite groups
On a class of groups with strongly embedded subgroup.
On a class of residually finite groups.
On a conjecture of Rhodes.
On a formula for the asymptotic dimension of free products
We prove an exact formula for the asymptotic dimension (asdim) of a free product. Our main theorem states that if A and B are finitely generated groups with asdim A = n and asdim B ≤ n, then asdim (A*B) = max n,1.
