Abstract
We apply Tannaka duality machinery to a one-generator category, which gives a general version of the FRT-construction for what we have called the homogeneous and non-homogeneous categories. In the case of n-homogeneous category, we present a Hopf algebra approach for solving the mixed Yang-Baxter type equations.
