Infinitesimal $\mathcal{R}$-matrices for some families of Hopf algebras

Lucrezia Bottegoni, Fabio Renda, Andrea Sciandra

Given a bialgebra $H$ such that the associated trivial topological bialgebra $H[[\hslash ]]$ admits a quasitriangular structure $\tilde{\mathcal{R}}=\mathcal{R}(1\otimes 1+\hbarχ+\mat…
