A little bit of Intuition for Corepresentations from Representations
Sorry about the left-right confusion (I think I am left-right-illiterate...).
If we have a left action $(g,x)\mapsto g.x$, but write it as a map $b:M\times G\to M$, $b(x,g)=g.x$, is that a left or a …

Towards a quantum version of Schur's orthogonality relations
The formula should be
$$\begin{align}
Y^{-1}(R\otimes 1)X&=Y^{-1}(I\otimes h)(Y^{-1}(Q\otimes 1)X)X
\\&=(I\otimes h\otimes I)\left(Y_{[13]}^{-1}Y_{[12]}^{-1}(Q\otimes 1\otimes 1)X_{[12]}X_{[13]}\righ …

The Irreducible Corepresentations of the eight-dimensional Kac-Paljutkin Quantum Group
The Kac-Paljutkin Quantum Group $A$ is self-dual, i.e. the dual space $A^*$ (which is of course again finite quantum group = finite-dimesional $C^*$-Hopf algebra, with the multiplication being the dua …
