Abstract
A weak bialgebra is known to be a special case of a bialgebroid. In this paper we study the relationship of this fact with the Tannaka theory of bialgebroids as developed in Phùng Hô Hai (Isr J Math 167(1):193–225, 2008). We obtain a Tannaka representation theorem with respect to a separable Frobenius fiber functor.
