The course introduces the mean curvature flow in the framework of geometric measure theory called the Brakke flow. Starting from the definition, the up-to-date research results will be presented.
A time-parametrized family of surfaces is called the mean curvature flow if the velocity of surface is equal to the mean curvature at each time and point. The mean curvature flow is a gradient flow of the surface area and its static counterpart is the minimal surface. Since the mean curvature flow has singularities, it is natural to consider the solution in the class of surfaces admitting singularities. Such class of surfaces can be expressed using the notion of varifold in geometric measure theory. In this course, starting from the definition of the Brakke flow, up-to-date research results are presented.
Students can: understand the definition of Brakke flow, understand the basic properties and can generalize the notion to more general flow, obtain some basic existence and regularity theories and can extend them to more general settings.
