Inverse mean curvature flow

Inverse mean curvature flow (IMCF) is a geometric flow that generalizes the concept of mean curvature flow, where instead of evolving a surface in the direction of its mean curvature, one evolves the surface in the opposite direction, that is, against the mean curvature. Mean curvature flow typically describes how a submanifold evolves over time under the influence of curvature, often leading to the minimization of surface area.
