“The geometric dimension of a discrete group G is the minimal dimension of a model for the classifying space BG. The action dimension of G is the minimal dimension of a manifold model. I will talk about some computations of the action dimensions for certain complexes of groups, including Artin groups, graph products, and fundamental groups of complex hyperplane complements.”
