本文分析了机构位形集合M的几何结构。使用李群语言,不需要任何正则性假设,人们可以给这个集合附加一个解析簇的结构。然后,我们将计算切锥在每个点的这个集合,而不引入任何坐标,我们将推出的结构M的奇点可能是什么。最后,给出了一些算例。
In this article, we analyse the geometrical structure of the set M of configurations of a mechanism. Using Lie groups language and without any hypothesis of regularity, one can attach to this set a structure of an analytic variety. We shall then compute the tangent cone at cach point of this set without introducing any coordinates and we shall deduce the structure of M whatever the singularity may be. Finally, some examples are studied.
