preLie 与 postLie 代数的 Ado 型定理的失效
Failure of Ado-type theorems for preLie and postLie algebras
AI总结:
本文在特征零域上构造二维 preLie 和 postLie 代数,证明它们无法嵌入有限维 preassociative 或 postassociative 代数的诱导结构,从而否定 Ado 型定理。
AI中文摘要:
在任意特征为零的域上,我们构造了一个二维 preLie 代数和一个二维 postLie 代数,它们分别不能嵌入到任何有限维 preassociative 或 postassociative 代数的相应诱导结构中。
英文摘要:
Over an arbitrary field of characteristic zero, we construct a two-dimensional preLie algebra and a two-dimensional postLie algebra that do not embed into the corresponding induced structures of any finite-dimensional preassociative or postassociative algebra, respectively.
