摘要:In this talk, we first give a complete description of normalized 3-cocycles on dihedral group D2n. By such a description we prove that the irreducible object in the category of Yetter-Drinfeld modules over the quasi-quantum groups D8 is the same as ordinary Yetter-Drinfeld  modules over D8. Thus they have the same corresponding Nichols algebras.
