AI总结:

本文基于Kronecker模完成两步幂零Leibniz代数分类,推广经典Heisenberg李代数得到不可分解Heisenberg Leibniz代数的复实情形,证明实幂零Leibniz代数可整体积分并给出应用,还揭示了积分Leibniz代数的李quandle与李群共轭的关系。

摘要:

本文通过与双线性型对相关的Kronecker模,给出了两步幂零Leibniz代数的完整分类。特别地,我们刻画了不可分解Heisenberg Leibniz代数的复情形与实情形,将其作为经典$(2n+1)$维Heisenberg李代数$\frak{h}_{2n+1}$的推广。随后我们利用S. Covez提出的Leibniz代数-李局部rack对应,证明实幂零Leibniz代数总存在整体积分。作为应用,我们积分了具有一维换位子理想的不可分解实幂零Leibniz代数。我们还证明,每个积分Leibniz代数的李quandle都由某个李群的共轭作用诱导,且该Leibniz代数就是这个李群的李代数。

英文摘要:

In this paper we give a complete classification of two-step nilpotent Leibniz algebras in terms of Kronecker modules associated with pairs of bilinear forms. In particular, we describe the complex and the real case of the indecomposable Heisenberg Leibniz algebras as a generalization of the classical $(2n+1)-$dimensional Heisenberg Lie algebra $\mathfrak{h}_{2n+1}$. Then we use the Leibniz algebras - Lie local racks correspondence proposed by S. Covez to show that nilpotent real Leibniz algebras have always a global integration. As an application, we integrate the indecomposable nilpotent real Leibniz algebras with one-dimensional commutator ideal. We also show that every Lie quandle integrating a Leibniz algebra is induced by the conjugation of a Lie group and the Leibniz algebra is the Lie algebra of that Lie group.
