平面偏序集的霍普夫代数的变形

Deformation of the Hopf algebra of plane posets

Loïc Foissy

摘要:

本文描述和研究了平面偏序集的霍普夫代数的两个乘积和余积的一个四参数变形。我们得到一族辫子霍普夫代数,一般是自对偶的.我们还证明,在一个特殊的情况下(当第二个参数为零,第一和第三个参数是相等的),这种变形是同构的,作为一个自对偶编织霍普夫代数,变形的自由拟对称函数的霍普夫代数。

英文摘要:

We describe and study a four parameters deformation of the two products and the coproduct of the Hopf algebra of plane posets. We obtain a family of braided Hopf algebras, generally self-dual. We also prove that in a particular case (when the second parameter goes to zero and the first and third parameters are equal), this deformation is isomorphic, as a self-dual braided Hopf algebra, to a deformation of the Hopf algebra of free quasi-symmetric functions.
