4. 2. Some non-linear geometric and kinetic evolutions and their approximations

   Author : Richards Grzhibovskis; Göteborgs universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; curvature flow; Willmore flow; convolution-thresholding; homothetic geometric flows; Boltzmann equation; deterministic methods; non-uniform grids; curvature flow;

   Abstract : 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. READ MORE
