Abstract: We give a characterization of Drinfeld centers of fusion categories asnon-degenerate braided fusion categories containing a Lagrangian algebra.Further we study the quotient of the monoid of non-degenerate braided fusioncategories modulo the submonoid of the Drinfeld centers and show that itsformal properties are similar to those of the classical Witt group.
