   Sammanfattning : This thesis deals with three non-linear evolution problems: mean curvature flow, Willmore flow, and the evolution of solutions to the space homogeneous Boltzmann equation. Generalized mean curvature flows are also considered. A major part of the study focuses on the construction of approximations to these evolutions. LÄS MER
