Abstract
We build a wonderful model for toric arrangements. We develop the "toric analog" of the combinatorics of nested sets, which allows us to define a family of smooth open sets covering the model. In this way, we prove that the model is smooth, and we give a precise geometric and combinatorial description of the normal crossing divisor. © 2011 The Author(s).
