Real analyticity of the modified Laplacian coflow
Real analyticity of the modified Laplacian coflow
Let (M,\psi(t))_{t\in[0, T]} be a solution of the modified Laplacian coflow (1.3) with coclosed G_{2}-structures on a compact 7-dimensional M. We improve Chen's Shi-type estimate [5] for this flow, and then show that (M,\psi(t),g_{\psi}(t)) is real analytic, where g_{\psi}(t) is the associate Riemannian metric to \psi(t), which answers a question …
