The space of closed G2-structures in a given cohomology class forms an infinite-dimensional manifold. We will present constructions of Levi-Civita connections for Sobolev-type metrics and their geodesic equations. If time allows, we will apply these structures to analyze the variational problems of torsion free G2-structures.
