Non-degeneracy of Hopf triplets
Tomoro Mochida
We study the relationship between semisimplicity and non-degeneracy for finite-dimensional Hopf triplets over a field of characteristic zero. The non-degeneracy condition appears i…

Cohomology for solutions of polygon equations
Serban Matei Mihalache, Tomoro Mochida
Polygon equations form a family of equations generalizing the pentagon equation. In this paper, we construct semi-simplicial sets of permitted colorings associated with set-theoret…
