由四面体架生成的余点霍普夫代数的表示
Representations of copointed Hopf algebras arising from the tetrahedron rack
摘要：
研究了仿射架$\Aff(\F_4,ω)$（又称四面体架）和2-上圈-1的Nichols代数上的余点霍普夫代数.我们研究了所谓的韦尔马模，并对所有的单模进行了分类。我们得出了这些代数是野表示型的，不是拟三角的，并分析了它们何时是球面的。
英文摘要：
We study the copointed Hopf algebras attached to the Nichols algebra of the affine rack $\Aff(\F_4,ω)$, also known as tetrahedron rack, and the 2-cocycle -1. We investigate the so-called Verma modules and classify all the simple modules. We conclude that these algebras are of wild representation type and not quasitriangular, also we analyze when these are spherical.
