摘要给定一个Lie n-代数,给出了它的积分Lie n-群的一个显式构造。这推广了Getzler在幂零$L_\inty$-代数情况下的工作。当应用于普通李代数时,我们的构造得到了相应的单连通李群的单纯分类空间。在Baez和Crans的弦Lie 2-代数的情况下,我们得到了他们的弦群模型的单纯神经。
Abstract Given a Lie n-algebra, we provide an explicit construction of its integrating Lie n-group. This extends work done by Getzler in the case of nilpotent $L_\infty $-algebras. When applied to an ordinary Lie algebra, our construction yields the simplicial classifying space of the corresponding simply connected Lie group. In the case of the string Lie 2-algebra of Baez and Crans, we obtain the simplicial nerve of their model of the string group.
