abstract = {<p style="text-align: justify;">A Ciarlet-Raviart type mixed finite element approximation is constructed
and analyzed for a class of fourth-order elliptic problems arising from solving various
gradient systems. Optimal error estimates are obtained, using a super-closeness relation between the finite element solution and the Ritz projection of the PDE solution.
Numerical results agree with the theoretical analysis.</p>},
