Numerical methods for some nonlinear transport equations in biology

报告人：Zhennan Zhou, Beijing International Center for Mathematical Research

摘要：In the first part, we first introduce a semi-discrete scheme for 2D KellerSegel equations based on a symmetrization reformation, which is equivalent to the convex splitting method and is free of any nonlinear solver.
