ResumenThe purpose of this paper is to analyze in detail the Hamiltonian formulation for the compact Gowdymodels coupled to massless scalar fields as a necessary first step toward their quantization. We will pay special attention to the coupling of matter and those features that arise for the S1 × S2 and S3 topologies that are not present in the well-studied T3 case—in particular the polar constraints that come from the regularity conditions on the metric. As a byproduct of our analysis we will get an alternative understanding, within the Hamiltonian framework, of the appearance of initial and final singularities for these models.
