AI总结:

本文研究了同伦李代数的表示范畴,并通过构造2移位泊松结构得到一致的微分2辫子,同时建立了表示范畴与Chevalley-Eilenberg代数上半自由dg-模之间的对称单向dg-等价。

摘要:

给定一个同伦李代数(即L_∞-代数)g,我们具体展示了如何将Lada-Markl的g-模(即表示)组装成一个对称单向的dg-范畴。考虑该dg-范畴的同伦2-范畴,我们从2移位的泊松结构构造微分2辫子,然后证明这样的微分2辫子在Cirio和Faria Martins的意义下是一致的。我们随后明确确定了与有限维同伦李代数相关的Chevalley-Eilenberg代数的微分,并构造了表示范畴与半自由dg-模 over Chevalley-Eilenberg代数之间的对称单向dg-等价。

英文摘要:

Given a homotopy Lie algebra (i.e. an $L_\infty$-algebra) $\mathfrak{g}$, we show concretely how the Lada-Markl $\mathfrak{g}$-modules (i.e. representations) assemble into a symmetric monoidal dg-category. Considering the homotopy 2-category of that dg-category, we construct infinitesimal 2-braidings from 2-shifted Poisson structures then show that such infinitesimal 2-braidings are coherent in Cirio and Faria Martins' sense. We then explicitly determine the differential of the Chevalley-Eilenberg algebra associated with a finite-dimensional homotopy Lie algebra and construct the symmetric monoidal dg-equivalence between the category of representations and the category of semi-free dg-modules over the Chevalley-Eilenberg algebra.
