✍ E.L. Green 📂 Article 📅 1995 🏛 Elsevier Science 🌐 English ⚖ 910 KB

Given a group-graded free associative algebra, we show that in many cases the path algebra associated to the covering coming from the grading has a Hopf algebra structure. Our structure on the path algehra is that of a quantum group for most of these constructions. Adding more restrictions, we creat

Finiteness Conditions, Co-Frobenius Hopf
✍ M Beattie; S Dăscălescu; L Grünenfelder; C Năstăsescu 📂 Article 📅 1998 🏛 Elsevier Science 🌐 English ⚖ 241 KB

Some finiteness conditions for infinite dimensional coalgebras, particularly right or left semiperfect coalgebras, or co-Frobenius Hopf algebras are studied. As well, examples of co-Frobenius Hopf algebras are constructed via a Hopf algebra structure on an Ore extension of a group algebra, and it is

Let A A be a Hopf algebra and ⌫ be a bicovariant first order differential calculus over A A. It is known that there are three possibilities to construct a differential Hopf algebra ⌫ n s ⌫ m rJ that contains ⌫ as its first order part. Corresponding to the three choices of the ideal J, we distinguish
