In this research project, we established the calssification of the singularities of solution surfaces of quasi-homogeneous first order partial differential equations, viscosity solutions of Hamilton-Jacobi equations with one-space variable and multivalued solutions of conservation laws which are a part of the main purpose. Moreover, we extend the theory ofviscosity solutions to the case when the second order non-degenerate equation with non-local effects (one-space variable). This research is important to describe the crystal growth with fascet surfaces. We also give some iimportant new examples of Riemannian manifolds with integrable geodesic flows.On the other hand, we have shown the existence of stable solutions for Ginzburg-Landau equation in a rotain domain. We have given a characterization of the symplectic and Lagarangian stablity of isotropic submanifolds with corank one by using a kind of transversality theorem. As a result on Algebraic and Geometric Topology we have developed an elementary tools for calculating the cohomology of heyper eliptic mapping class groups over finite fields.These results are contained in the areas of the border of Geometry and Analysis. We expect to apply these results for studying Partial Differentail Equations in near future.

在本研究项目中，我们建立了准齐次一阶偏微分方程解曲面奇异性的分类、具有单空间变量的Hamilton-Jacobi方程的粘性解和守恒定律的多值解，这是主要部分的一部分。目的。此外，我们将粘度解理论扩展到具有非局部效应（单空间变量）的二阶非简并方程的情况。这项研究对于描述 fascet 表面的晶体生长具有重要意义。我们还给出了具有可积测地流的黎曼流形的一些重要的新例子。另一方面，我们证明了Ginzburg-Landau方程在rotain域中稳定解的存在性。我们利用一种横断定理给出了具有科兰克一的各向同性子流形的辛稳定性和拉格朗日稳定性的刻画。作为代数和几何拓扑的结果，我们开发了一种基本工具，用于计算有限域上的高椭圆映射类群的上同调。这些结果包含在几何和分析的边界区域中。我们期望在不久的将来将这些结果应用于研究偏微分方程。
