特殊A_ \infty -双代数的结构关系

Structure Relations in Special A_\infty-bialgebras

Ronald Umble

摘要:

我们计算了特殊A_ \infty -双代数中的结构关系,这些双代数的运算仅限于定义底层A_ \infty -(co)代数子结构的运算。这样的双代数表现为某些闭路空间的同调。一般的A_ \infty -双代数的结构关系依赖于置换面体的组合,而这里只需要Stasheff的结合面体。

英文摘要:

We compute the structure relations in special A_\infty-bialgebras whose operations are limited to those defining the underlying A_\infty-(co)algebra substructure. Such bialgebras appear as the homology of certain loop spaces. Whereas structure relations in general A_\infty-bialgebras depend upon the combinatorics of permutahedra, only Stasheff's associahedra are required here.
