| Research Abstract |
We have been developed the original method for differential equations. We obtain all exact solutions and derive transcendental equations equivalent to the global bifurcation structure of the given differential equations. We have developed this method and applied it various problems. Especially, as for a cross-diffusion equation in 1 dimensional case, we have discovered various devises to analyze transcendental equations, and obtained the method to show the global bifurcation structure. Furthermore, we have started to investigate the stability of stationary solutions including multidimensional case. We have also reveal the blowup phenomena of curvature for plane elastic closed curves and the global structure of all curves.
