Products of Free Groups in the Unit Group of Integral Group Rings II
We classify all the finite groupsG, such that the group of units ofZGcontains a subgroup of finite index which is isomorphic to a direct product of nonabelian free groups.

On free groups in the unit group of integral group rings
We present a short history of the following problem: Classify the finite groups G, so that the group of units of the integral group ring Z G contains a subgroup of finite index isomorphic to a direct product of nonabelian free ...

Harmonic maps, SU (N) skyrme models and yang-mills theories [PDF]
This thesis examines the construction of static solutions of (3+l)-dimensional SU{N) Skyrme models, usual and alternative, and pure massive SU(N) Yang-Mills theories.

Van Kampen’s embedding obstruction for discrete groups [PDF]
We give a lower bound to the dimension of a contractible manifold on which a given group can act properly discontinuously. In particular, we show that the n -fold product of nonabelian free groups cannot act properly discontinuously on ℝ 2 n −1 .Peer ...

Classification of free actions on complete intersections of four quadrics [PDF]
In this paper we classify all free actions of finite groups on Calabi-Yau complete intersection of four quadrics in ℙ 7, up to projective equivalence. We get some examples of smooth Calabi-Yau three-folds with large nonabelian fundamental groups. We also

Translation lengths of outer automorphisms of finitely generated free-by-finite groups
Bestvina, Feighn and Handel proved that every subgroup of the outer automorphism group, (Formula presented.) of the free group of rank n is either virtually finitely generated abelian or contains a nonabelian free group. In this note we consider the more
