First, Lou-Ni-Yotsutani [DCDS 2004] investigated a limiting equation to a cross-diffusion equation that appears in mathematical biology. We showed that it has different kinds of singular solutions and revealed the structure of all solutions.This problem is a nonlocal nonlinear elliptic boundary problem, for which no method was known to solve it. We discovered a new method, which are the combination of the modern method of PDE and classical analysis and algebra.There are a lot of interesting problems for which our method is applicable.A problem of the Oseen's spiral flow is one of them, for which we obtained the complete bifurcation diagram in Ikeda-Kondo-Okamoto-Yotsutani [CPAA 2003].Matsumoto-Murai-Yotsutani [Pisa, 2005] gave the complete answer for a problem to determine curves with the least energy under the given length.Second, Kosugi-Morita-Yotsutani [CPAA 2005, J.Math.Phy. 2005] have revealed the complete Global bifurcation branches one dimensional Ginzburg-Landau equations with periodic boundary conditions.

首先，Lou-Ni-Yotsutani[DCDS 2004]研究了数学生物学中出现的交叉扩散方程的一个极限方程。我们证明了它有不同的奇异解，并揭示了所有解的结构，该问题是一个非局部的非线性椭圆型边值问题，没有已知的方法来求解它。我们发现了一种新的方法，它是现代偏微分方程组方法与经典分析和代数的结合。我们的方法适用于许多有趣的问题。Oseen螺旋流问题就是其中之一，我们在Ikeda-Kondo-Okamoto-Yotsutani[CPAA 2003]中得到了完整的分岔图。MatSumoto-Murai-Yotsutani[Pisa，2005]给出了在给定长度下确定能量最小的曲线问题的完整答案。2005]揭示了具有周期边界条件的一维Ginzburg-Landau方程的完整的全局分支。
