Accurate expression of the second moments for Meyer-Knig-Zeller operators defined on the triangle;

Rate of convergence for Meyer-Knig-Zeller operators with Jacobi-weights;

In this paper,we first construct Jacobi-weights of non-product form,then study the convergence rate of Meyer-Konig-Zeller operators with Jacobi-weights on a simplex by making use of multivariate decompose skills and results of Meyer-Knig-Zeller operators and finally,obtain the approximation direct theorem.
