符号排列空间上的一个代数结构
An algebra structure on the linear span of signed permutations
-
摘要: 由所有符号排列生成的线性空间上代数结构的相关研究在过去二十年备受关注。本研究在该空间上引入一种新的代数结构,并证明将每个符号排列映为其对应的标准排列所诱导的映射,是从这一新定义的代数到Malvenuto-Reutenauer Hopf代数的满代数同态。Abstract: The study of algebra structures on the linear span of all signed permutations has attracted considerable attention over the past two decades. In this work, we introduce a new algebra structure on this underlying space and show that the map which sends each signed permutation to its corresponding standard permutation induces a surjective algebra homomorphism from the newly defined algebra to the Malvenuto-Reutenauer Hopf algebra.
