Pachner's 3-3 relations and Hopf algebras R. M. Kashaev |
|||
Аннотация: I will discuss a particular construction of solutions to Pachner's 3-3 relation in 4 dimensions by using the structure maps of Hopf algebras and duality pairings. In the particular case of self-dual bi-commutative Hopf algebras there are solutions carrying the full symmetry of the regular 4-dimensional simplex. Язык доклада: английский |
