DESCRIPTION:The geometric dimension of a torsion-free group G is the minim
 um dimension of a model for BG by a CW complex.&nbsp\; Its action dimensio
 n is the&nbsp\;minimum dimension of a model for BG by a manifold. I will d
 iscuss some recent work with Kevin Schreve and Giang Le in which we comput
 e the action dimension of Artin groups\, graph products of groups&nbsp\;an
 d other examples of groups which are given as simple complexes of groups.
