Iglesias, F. Castaño et C. N.st.sescu,, The Quotient Category of a Graded MoritaTakeuchi Context, Acta mathematica Sinica. English series (Print) , 22(1), 2006, pp. 123-130
In this paper, we offer a graded equivalence between the quotient categories defined by any graded Morita.Takeuchi context via certain modifications of the graded cotensor functors. As a consequence, we show a commutative diagram that establish the relation between the closed objects of the categories gr C and M C, where C is a graded coalgebra
