Physics for algebraists: Non-commutative and non-cocommutative Hopf algebras by a bicrossproduct construction. (English) Zbl 0694.16008

The “Physics for algebraists” is in the context of quantum mechanics combined with gravity, describing Yang-Baxter equations, position observables, momentum space, momentum and position quantization, etc. This physics leads to the search for self-dual algebraic structures, and finally to a bicrossproduct construction of non-commutative and non- cocommutative Hopf algebras. There are numerous examples, including a modification of the Weyl algebra. In the appropriate context, the compatibility conditions on the structure maps reduce to the classical Yang-Baxter equations. An example is given related to the double Hopf algebra D(H) of Drinfeld.
