As was shown by a part of the authors, for a given $(2,3,5)$ -distribution $D$ on a five-dimensional manifold $Y$ , there is, locally, a Lagrangian cone structure $C$ on another five-dimensional manifold $X$ which consists of abnormal or singular paths of $(Y,D)$ . We give a characterization of the class of Lagrangian cone structures corresponding to $(2,3,5)$ -distributions. Thus, we complete the duality between $(2,3,5)$ -distributions and Lagrangian cone structures via pseudo-product structures of type $G_{2}$ . A local example of nonflat perturbations of the global model of flat Lagrangian cone structure which corresponds to $(2,3,5)$ -distributions is given.

(2, 3, 5)-分布和拉格朗日锥结构的对偶性
正如部分作者所表明的,对于给定的$(2,3,5)$ -分配$D$ 在五维流形上$Y$ , 局部存在拉格朗日锥结构$加元 在另一个五维流形上$X$ 它由异常或奇异的路径组成$(Y,D)$ . 我们给出了对应于的拉格朗日锥结构类的特征$(2,3,5)$ -分布。因此,我们完成了之间的对偶$(2,3,5)$ -分布和拉格朗日锥结构通过类型的伪积结构$G_{2}$ . 平面拉格朗日锥结构的全局模型的非平面扰动的局部示例,对应于$(2,3,5)$ -给出了分布。
