树形代数的扩展结构

Extending Structures for Dendriform Algebras

Yuanyuan Zhang, Junwen Wang

AI总结:

本文研究树形代数的扩展结构,定义统一积、匹配对等概念,解决扩展与分解问题,并引入形变映射用于分类补问题。

摘要:

本文致力于研究树形代数的扩展结构。首先,我们定义了树形代数的扩展数据和统一积,并从理论上解决了扩展结构问题。作为应用,我们将旗标数据视为扩展结构的一个特例,并给出了扩展结构问题的一个实例。其次,我们引入了树形代数的匹配对和双交叉积,并从理论上解决了树形代数的分解问题。此外,我们还引入了余循环半直积和非阿贝尔半直积作为统一积的特例。最后,我们在树形扩展结构(更一般的情形)上定义了形变映射,该映射不一定是匹配对,在分类补问题中更为实用。

英文摘要:

In this paper, we devote to extending structures for dendriform algebras. First, we define extending datums and unified products of dendriform algebras, and theoretically solve the extending structure problem. As an application, we consider flag datums as a special case of extending structures, and give an example of the extending structure problem. Second, we introduce matched pairs and bicrossed products of dendriform algebras and theoretically solve the factorization problem for dendriform algebras. Moreover, we also introduce cocycle semidirect products and nonabelian semidirect products as special cases of unified products. Finally, we define the deformation map on a dendriform extending structure (more general case), not necessary a matched pair, which is more practical in the classifying complements problem.
