Abstract

We define the right regular dual of an object X in a monoidal category C; and give several results regarding the weak rigid monoidal category. Based on the definition of the right regular dual, we construct a weak Hopf algebra structure of H = End(F) whenever (F; J) is a fiber functor from category C to V ec and every XC has a right regular dual. To conclude, we give a weak reconstruction theorem for a kind of weak Hopf algebra.
