Abstract We consider the Laplacian “co-flow” of G 2 -structures: ∂ ∂ t ψ = − Δ d ψ where ψ is the dual 4-form of a G 2 -structure φ and Δ d is the Hodge Laplacian on forms. Assuming short-time existence and uniqueness, this flow preserves the condition of the G 2 -structure being coclosed ( d ψ = 0 ). We study this flow for two explicit examples of coclosed G 2 -structures with symmetry. These are given by warped products of an interval or a circle with a compact 6-manifold N which is taken to… Expand
