Outline of Final Research Achievements

(1) We established a mathematical method analyzing spatial patterns in some models of cell polarity. Moreover, we gave a condition allowing the instability of uniform states in a model of conserved diffusion systems coupled on the boundary. (2) We proposed a numerically efficient scheme for simulations of cell-cell adhesion model. (3) We improved an infectious model of virus by taking a delay effect into account and verified that the model matches experimental data.
