On Posets and Hopf Algebras

Advances in Mathematics, 1996
Given the collection of types \(\overline{P}\) of finite posets \(P\) with elements \(\widehat{0}\) and \(\widehat{1}\), the linear space \(I\) over a field \(K\) whose basis is the set of types is in a natural way an algebra, if \(\overline{P}\otimes\overline{Q}=\overline{P\otimes Q}\), where \(P\otimes Q\) is the product poset, extended linearly. If \

On Normal Hopf Subalgebras of Semisimple Hopf Algebras [PDF]

Algebras and Representation Theory, 2010
A criterion for subcoalgebras to be invariant under the adjoint action is given generalizing Masuoka's criterion for normal Hopf subalgebras. At the level of characters, the image of the induction functor from a normal Hopf subalgebra is isomorphic to the image of the restriction functor.

Cat weak Hopf algebras(Cat弱Hopf代数)

Zhejiang Daxue xuebao. Lixue ban, 2017
首先引入pre-cat弱Hopf代数和cat弱Hopf代数来刻画具有投射的弱Hopf代数的性质，并建立pre-cat弱Hopf代数的张量范畴，证明了pre-cat弱Hopf代数是cat弱Hopf代数的充要条件，从而推广了LODAY引入的cat-群和cat Hopf代数的相应结论.

Cohomology of Hopf C^* -Algebras and Hopf Von Neumann Algebras [PDF]

Proceedings of the London Mathematical Society, 2001
In this article, we will define two canonical cohomology theories for Hopf $C^*$-algebras and for Hopf von Neumann algebras (with coefficients in their bicomodules). We will then study the situations when these cohomologies vanish. The cases of locally compact groups and compact quantum groups will be considered in more details.

Weak Hopf symmetry and tube algebra of the generalized multifusion string-net model

Journal of High Energy Physics
We investigate the multifusion generalization of string-net ground states and lattice Hamiltonians, delving into their associated weak Hopf symmetries. For the multifusion string-net, the gauge symmetry manifests as a general weak Hopf algebra, leading ...
