Abstract: Closed G2-Structures are of profound importance for constructing metrics with holonomy G2, however, we know very little about the space of closed G2-Structures on any given compact, orientable, spin 7-manifold. In particular, we do not know if such a compact 7-manifold may admit an exact G2-Structure. We would also like to know more about soliton solutions of the Laplacian flow, which is a geometric flow that aims to provide insight into when we may perturb a G2-Structure with torsion to a torsion-free G2-Structure. We exploit the fact that the G2-Structure underlying a (shrinking or expanding) closed Laplacian soliton is exact to study these solitons as a special class of exact G2-Structure. This approach turns out to be quite powerful as it provides a unified picture for the established results for such solitons in the literature while motivating new results for solitons as special cases of results which hold for exact G2-Structures more generally.
