The Structure Theorem for Weak Module Coalgebras
Yu. Wang, L. Yu. Jang Nanjing Agricultural University
Abstract:
Let $H$ be a weak Hopf algebra, let $C$ be a weak right $H$-module coalgebra, and let $\overline C=C/C\cdot \operatorname{Ker}\operatorname{\sqcap}^{L}$. We prove a structure theorem for weak module coalgebras, namely, $C$ is isomorphic as a weak right $H$-module coalgebra to a weak smash coproduct $\overline C\times H$ defined on a $k$-space
$$
\{\Sigma c_{(0)}\otimes h_2\varepsilon(c_{(-1)}h_1)\mid c\in C,\,h\in H\}
$$
if there exists a weak right $H$-module coalgebra map $\phi\colon C\to H$.
Keywords:
weak Hopf algebra, weak Hopf bicomodule, weak comodule coalgebra, weak smash coproduct, weak module coalgebra.
