The study demonstrates that convex ancient solutions of mean curvature flow with Type I curvature growth are limited to being either spherical, cylindrical, or planar. It also proves a similar statement for flows described by a specific class of curvature functions that are convex or concave in the second fundamental form. These results do not require the assumption of non-collapsing interior.
We show that every convex ancient solution of mean curvature flow with Type I curvature growth is either spherical, cylindrical, or planar. We then prove the corresponding statement for flows by a natural class of curvature functions which are convex or concave in the second fundamental form. Neither of these results assumes interior noncollapsing.
