    "abstract": "Central bialgebras in a braided category $\\C$ are algebras in the center of\nthe category of coalgebras in $\\C$. On these bialgebras another product can be\ndefined, which plays the role of the opposite product. Hence, coquasitriangular\nstructures on central bialgebras can be defined. We prove some properties of\nthe antipode on coquasitriangular central Hopf algebras and give a\ncharacterization of central bialgebras.",
