“Short-time behaviour of a modified Laplacian coflow of G2-structures”

We first consider the Laplacian co-flow of co-closed G2-structures on compact 7-dimensional manifolds. This is the heat flow for the dual 4-form of a G2-structure. However this flow turns out to be not even weakly parabolic, unlike a similar flow for the G2-structure 3-form. We then modify this flow to make it weakly parabolic in the direction of closed forms and prove short time existence and uniqueness of solutions for this new flow.
