Sep 21, 2021 at 1:03 | comment | added | user378654 | The form of Harnack inequality they derive is straightforward to obtain with constants depending on, say, the supremum of the full curvature tensor: it can be derived from the standard Harnack inequality and elliptic/parabolic estimates. The key point is that their estimate depends only on a one-sided bound on the Ricci curvature, which is drastically less information and makes it relevant to geometric analysts. That said, I can't comment on specific instances of this form of Harnack in the literature before them (or dating back to Bernstein); their work likely popularized it to some extent. | |
