Résumé :
A quasitriangular bialgebra H has a universal R-matrix which provides solutions of the quantum Yang-Baxter equation in any representation. In a similar way, a quasitriangular coideal subalgebra B of H has a universal K-matrix which provides solutions of the reflection equation. In this talk I will discuss different incarnations of this notion. As an example I will consider quantum symmetric pairs of finite type. I will explain how to extend previous work to show that the corresponding coideal subalgebras are quasitriangular.
