A finite volume scheme for the Patalk-Keller segel model of chemotaxis

报告摘要：

  A finite volume scheme is presented to discretize the PKS model for chemosensitive movements (application in biology for the study of cell motion). On the one hand, we prove existence and uniqueness of a numerical solution to the proposed scheme. On the other hand, we give a priori estimates and establish a threshold on the initial mass, for which we show that the numerical approximation converges to the solution of the PKS system. Finally, numerical simulations are performed to verify accuracy and the properties of the scheme.
