Roughly speaking, the category $\mathcal{Z}(\mathcal{C})$ is the universal object through which strict braided functors to $\mathcal{C}$ factor (see Kassel Proposition XIII.4.3. for details). | |

| Feb 3, 2018 at 6:06 | comment | added | Mathematician 42 | As for the last question: The category of Yetter-Drinfeld modules of $H$ is equivalent to the category of modules over the Drinfeld double $D(H)$. But I guess this merely shifts your question to why the Drinfeld double is defined the way it is. | |
