Kac-Paljutkin量子群作为量子SU(2)的量子子群

Kac-Paljutkin Quantum Group as a Quantum Subgroup of the Quantum SU(2)

Megumi Kitagawa

摘要:

我们证明了Kac-Paljutkin霍普夫代数是$C(SU_{-1}(2))$的商,这意味着相应的量子群$C(SU_{-1}(2))$可以看作是$SU_{-1}(2)$的量子子群.结合Kac-Paljutkin Hopf代数的余表示范畴是与Krein 4-群相联系的Tambara-Yamagami张量范畴这一事实和霍普夫代数的分次扭曲方法,构造了Hopf *-同态.

英文摘要:

We show that the Kac-Paljutkin Hopf algebra appears as a quotient of $C(SU_{-1}(2))$, which means that the corresponding quantum group $G_{KP}$ can be regarded as a quantum subgroup of $SU_{-1}(2)$. We combine the fact that corepresentation category of the Kac-Paljutkin Hopf algebra is a Tambara-Yamagami tensor category associated with the Krein 4-group and the method of graded twisting of Hopf algebras, to construct the Hopf *-homomorphism.
