Outline of Final Research Achievements

I proved that the discrete KdV equation (the bilinear form, the nonlinear form) and the discrete Toda equations (semi-infinite boundary conditions, molecular boundary conditions, periodic boundary conditions) have the Laurent property, the irreducibility and co-primeness.
The other hand, from recent time-lapse imaging experiments on the dynamics of endothelial cells (ECs) in angiogenesis, I proposed a mathematical model of ECs by methods of a discrete system and a ultra-discrete discrete system. Furthermore, I proposed a continuous model and an extended model incorporating the influence of vascular endothelial growth factor (VEGF).
