摘要

我们证明了加权有向图的代数公式导致引入一个具有两个协积Δ和Δ ~的k向量空间，验证了所谓的协结合性破缺方程(Δ ~⊗id)Δ=(id⊗Δ)Δ ~。这样的空间叫做l -协代数。构造了这种空间的显式示例，并给出了图论与协协代数之间的联系。

An algebraic framework of weighted directed graphs

We show that an algebraic formulation of weighted directed graphs leads to introducing a k-vector space equipped with two coproducts Δ and Δ˜ verifying the so-called coassociativity breaking equation (Δ˜⊗id)Δ=(id⊗Δ)Δ˜. Such a space is called an L-coalgebra. Explicit examples of such spaces are constructed and links between graph theory and coassociative coalgebras are given.
