摘要：

The parameter estimation problem for the convection coefficient in elliptic equations is considered in the class of L-n(2)-vector fields. The optimality system is characterized and the convergence of the gradient method is proved. To apply the SQP-method to the singular optimality system, a modification involving a feasibility step in the primal and dual variables is introduced. The resulting algorithm has a second-order convergence rate. Numerical experiments are included.
