结合代数和树状代数上的O-算子

O-operators on associative algebras and dendriform algebras

Chengming Bai, Li Guo, Xiang Ni

摘要:

O-算子是Rota-Baxter算子的相对形式,在李代数中,它起源于经典杨-巴克斯特方程的算子形式。我们将著名的由Rota-Baxter代数构造树状双代数和树状三代数的方法推广到由O-算子构造树状双代数和树状三代数。然后我们证明了O-算子的这种构造给出了所有树状双代数和三代数。此外,可逆O-算子的某些等价类与树状双代数和三代数的某些等价类之间存在双射。

英文摘要:

An O-operator is a relative version of a Rota-Baxter operator and, in the Lie algebra context, is originated from the operator form of the classical Yang-Baxter equation. We generalize the well-known construction of dendriform dialgebras and trialgebras from Rota-Baxter algebras to a construction from O-operators. We then show that this construction from O-operators gives all dendriform dialgebras and trialgebras. Furthermore there are bijections between certain equivalence classes of invertible O-operators and certain equivalence classes of dendriform dialgebras and trialgebras.
