我们证明了由有限维向量空间组成的持久性模块(对于全序索引集)是区间模块的直和。结果扩展到图像和内核上具有降链条件的持久化模块。
We show that a persistence module (for a totally ordered indexing set) consisting of finite-dimensional vector spaces is a direct sum of interval modules. The result extends to persistence modules with the descending chain condition on images and kernels.
