从Hopf代数到辫子$L_\infty$ -代数

From Hopf algebra to braided $L_\infty$-algebra

Clay J. Grewcoe, Larisa Jonke, Toni Kodzoman, George Manolakos

摘要:

证明了一个$L_\infty$ -代数可以推广到一个具有余微分的分次Hopf代数.然后,我们用Drinfel'd扭曲来扭曲这个扩展的$L_\infty$ -代数,同时扭曲它的模.将$L_\infty$ -代数作为它自己的(Hopf)模,得到了最近提出的辫子$L_\infty$ -代数. Hopf代数态射与严格$L_\infty$ -态射一致,而辫状$L_\infty$ -态射定义了扭曲$L_\infty$ -代数的更一般的$L_\infty$ -作用.

英文摘要:

We show that an $L_\infty$-algebra can be extended to a graded Hopf algebra with a codifferential. Then we twist this extended $L_\infty$-algebra with a Drinfel'd twist, simultaneously twisting its modules. Taking the $L_\infty$-algebra as its own (Hopf) module, we obtain the recently proposed braided $L_\infty$-algebra. The Hopf algebra morphisms are identified with the strict $L_\infty$-morphisms, while the braided $L_\infty$-morphisms define a more general $L_\infty$-action of twisted $L_\infty$-algebras.
