Real analyticity of the modified Laplacian coflow

Abstract Let be a solution of the modified Laplacian coflow (1.3) with coclosed ‐structures on a compact 7‐dimensional . We improve Chen's Shi‐type estimate [Q. J. Math. 69 (2018), no. 3, 779–797] for this flow, and then show that is real analytic, where is the Riemannian metric associated to , which answers a question proposed by Grigorian in [Fields Inst. Commun. 84 (2020), 271–286]. Consequently, we obtain the unique continuation results for this flow.
