霍普夫颤动

Hopf quivers

Claude Cibils, Marc Rosso

摘要:

本文利用类似于Cayley图的Hopf箭图对路余代数上的分次霍普夫代数结构进行了分类.描述除了涉及余积的规范公式外,还涉及乘积的公式。这使得明确的量子洗牌产品利用自然元素在一个霍普夫双模有一个简单的“几何”的解释,在广义上,而不是系统地工作与右或左coinvariants。

英文摘要:

We classify graded Hopf algebras structures over path coalgebras, that is over free pointed coalgebras, using Hopf quivers which are analogous to Cayley graphs. The description involves formulas for the product besides the canonical formulas for the coproduct. This makes explicit the quantum shuffle product making use of natural elements in a Hopf bimodule having a simple "geometrical" interpretation in the quiver sense, rather than working systematically with right or left coinvariants.
