利用动力系统理论和三维加权射影空间CP3(p,q,r,s)研究了第一、第二和第四类Painlevé方程,其权(p,q,r,s)由方程的牛顿图或向量场的奇异变形确定.借助于CP3(p,q,r,s)的轨道结构,给出了方程的奇异规范形,Painlevé性质的简单证明和初始条件空间的辛图集.特别地,对于第一个Painlevé方程,我们几何地导出了一个著名的Painlevé变换,证明了它是具有全纯辛形式的某个代数曲面的Darboux坐标。从加权射影空间的角度研究了仿射Weyl群、Dynkin图和Boutroux坐标。
The first, second and fourth Painlevé equations are studied by means of dynamical systems theory and three dimensional weighted projective spaces C P 3 (p, q, r, s) with suitable weights (p, q, r, s) determined by the Newton diagrams of the equations or the versal deformations of vector fields. Singular normal forms of the equations, a simple proof of the Painlevé property and symplectic atlases of the spaces of initial conditions are given with the aid of the orbifold structure of C P 3 (p, q, r, s). In particular, for the first Painlevé equation, a well known Painlevé's transformation is geometrically derived, which proves to be the Darboux coordinates of a certain algebraic surface with a holomorphic symplectic form. The affine Weyl group, Dynkin diagram and the Boutroux coordinates are also studied from a view point of the weighted projective space.
