Pointed Drinfeld center functor

Understand

In this work, using the functoriality of Drinfeld center of fusion categories, we generalize an earlier result on the functoriality of full center of simple separable algebras in a fixed fusion category to all fusion categories.

• This generalization produces a new center functor, which involves both Drinfeld center and full center and will be called the pointed Drinfeld center functor.
• We prove that this pointed Drinfeld center functor is a symmetric monoidal equivalence.
• It turns out that this functor provides a precise and rather complete mathematical formulation of the boundary-bulk relation of 1+1D rational conformal field theories (RCFT).
