摘要

Heckenberger引入了有限维对角型Nichols代数的Weyl群。我们用一个高张量来代替它的编织矩阵，并给出了一个进一步生成Weyl群的构造。阿贝尔上同调理论给出了与这样一个张量相关的更高编织存在的证据。

Higher Braidings of Diagonal Type

Heckenberger introduced the Weyl groupoid of a finite-dimensional Nichols algebra of diagonal type. We replace the matrix of its braiding by a higher tensor and present a construction which yields further Weyl groupoids. Abelian cohomology theory gives evidence for the existence of a higher braiding associated to such a tensor.
