In this work we study the space of group homomorphisms Hom(Γ,G) from a geometric
and simplicial point of view. The case in which the source group is a free abelian
group of rank n is studied in more detail since this space can be identified with the space of commuting n-tuples of elements from G. This latter case is of
particular interest when the target is a Lie group.
The simplicial approach allows us to to construct a family of spaces that filters the
classifying space of a group by filtering group theoretical information of the given
group. Namely, we use the lower central series of free groups to construct a
family of simplicial subspaces of the bar construction of the classifying space of
a group. The first layer of this filtration is studied in more detail for
transitively commutative (TC) groups.
