一个包含Poisson运算的Hopf运算

On a Hopf operad containing the Poisson operad

Frederic Chapoton

摘要:

引入了一个新的Hopf运算Ram,它包含了著名的Poisson运算和作者以前引入的Bessel运算。此外,在由生成元和关系给出的代数集合上引入了一个cooperad R的结构,这些生成元和关系与A型超平面排列的上同调的Arnold关系有相似之处.定义了一个从操作数Ram到R的对偶操作数的映射,我们猜想它是一个同构。

英文摘要:

A new Hopf operad Ram is introduced, which contains both the well-known Poisson operad and the Bessel operad introduced previously by the author. Besides, a structure of cooperad R is introduced on a collection of algebras given by generators and relations which have some similarity with the Arnold relations for the cohomology of the type A hyperplane arrangement. A map from the operad Ram to the dual operad of R is defined which we conjecture to be a isomorphism.
