Collapsed pseudo-locality conjecture with scalar-curvature control
Collapsed pseudo-locality conjecture with scalar-curvature control
Let . There should exist positive constants and such that, if is an -dimensional Ricci flow with complete time slices and, for some ,
then for every ,
Collapsed pseudo-locality conjecture. The asserted curvature estimate should hold even when the initial unit ball is Gromov--Hausdorff close to a lower-dimensional Euclidean ball. This would provide a pseudo-locality principle compatible with collapse, beyond the usual noncollapsing hypotheses; examples cited in the source show that simply deleting all local volume assumptions without scalar-curvature control cannot work.
