Abstract

In this paper, we extend Lotay–Wei’s Shi-type estimate from Laplacian flow to more general flows of G2 structures including the modified Laplacian co-flow. Then we prove a version of κ-non-collapsing theorem. We will use both of them to study finite-time singularities of general flows of G2 structures.
