To classify the finite dimensional pointed Hopf algebras with G = McL we obtain the representatives of conjugacy classes of G and all character tables of centralizers of these representatives by means of software GAP. 2000 Mathematics Subject Classification: 16W30,20D06 keywords: GAP, Hopf algebra, sporadic simple group, character. 0. Introduction This article is to contribute to the classifica...

We show that any pivotal Hopf monoid $H$ in a symmetric monoidal category $\mathcal{C}$ gives rise to actions of mapping class groups oriented surfaces genus $g \geq 1$ with $n boundary components. These group are given by homomorphisms into the automorphisms certain Yetter-Drinfeld modules over $H$. They associated edge slides embedded ribbon graphs generalise chord diagrams. give concrete des...

In this paper, dynamical analysis is presented for a group of unicycles in leader-follower formation. The equilibrium formations were characterized along with the local stability analysis. It was demonstrated that with the variation in control gain, the collective dynamics might undergo Andronov-Hopf and Fold-Hopf bifurcations. An increase in the number of unicycles increase the vigor of quasi-...

We consider issues related to the origins, sources and initial motivations of the theory of Hopf algebras. We consider the two main sources of primeval development: algebraic topology and algebraic group theory. Hopf algebras are named from the work of Heinz Hopf in the 1940’s. In this note we trace the infancy of the subject back to papers from the 40’s, 50’s and 60’s in the two areas mentione...
