Global $\varepsilon$-regularity for 4-dimensional Ricci flow with integral scalar curvature bound

Abstract

Ge-Jiang (Geom Funct Anal 27:1231-1256, 2017) proved global $\varepsilon$-regularity for 4-dimensional Ricci flow with bounded scalar curvature. In this note, we extend this result to 4-dimensional Ricci flow with integral bound on the scalar curvature.Comment: 9 pages, all comments are welcom
