Query: Multifusion Categories and Finite Semisimple 2-Categories   The 3-categories of semisimple 2-categories and of multifusion categories are
shown to be equivalent. A weakening of the notion of fusion 2-category is
introduced. Multifusion 2-categories are defined, and the fusion rule of the
fusion 2-categories associated to certain pointed braided fusion categories is
described.
