摘要翻译:
我们描述了余维一中全纯网的整体结构,特别是它们的奇异性(焦散性)。引入了在正则点附近不感兴趣的各种概念,如类型、可约性、拟光滑性、CI性质(完全交)、二元性等。例如,我们证明了在复射影空间上全局定义的网的代数性至少可以在它的焦散性(二叉性)上得到,如果每个不可约分量是CI,并且该网是拟光滑的。.

英文摘要:
We describe the global structure of holomorphic webs in codimension one, and in particular their singularity (caustic). Various concepts are introduced, which have no interest locally near a regular point, such as the type, the reducibility, the quasi-smoothness, the CI property (complete intersection), the dicriticity... We prove for instance that the algebraicity of a web globally defined on a complex projective space may be readen on its caustic (dicriticity), at least if each irreducible component is CI, and the web quasi-smooth. .
