Anisotropic diffusion chemotaxis models derived from stochastic equations

Abstract

In this talk, we shall discuss the stochastic modeling of chemotaxis and derive an anisotropic diffusion chemotaxis models from the Langevin stochastic equations which takes into account the movement persistence. The various techniques, such as mean-filed theory, minimization principle, moment closure and scaling argument, will be used to carry out the results. In addition the stochastic simulations exhibiting the chemotactic behavior will be presented.
