Existence, Convergence and Limit Map of the Laplacian Flow

Abstract

We prove short time existence and uniqueness of the Laplacian flow starting at an arbitrary closed G2G_2-structure. We establish long time existence and convergence of the Laplacian flow starting near a torsion-free G2G_2-structure. We analyze the limit map of the Laplacian flow in relation to the moduli space of torsion-free G2G_2-structures. We also present a number of results which constitute a fairly complete algebraic and analytic basis for studying the Laplacian flow.
