Abstract:
The geometric dimension of a torsion-free group G is the
minimum dimension of a model for BG by a CW complex. Its action dimension is the minimum dimension
of a model for BG by a manifold. I will
discuss some recent work with Kevin Schreve and Giang Le in which we compute
the action dimension of Artin groups, graph products of groups and other examples of
groups which are given as simple complexes of groups.
