Remarks on Tannaka recovery of coalgebras

[摘要] In virtue of some highly generalized Tannaka-Krein-type reconstruction theorems, it is natural to ask which functors F:C-->V are equivalent to the forgetful functor U-H : Comod(H)-->V for some V-Hopf-algebra H. We will study in this paper the question whether Comod(coend(F)) congruent to C when F=U-C for a coalgebra C and V is a module category over a ring. (C) 1999 Elsevier Science B.V.
