摘要：

We present a method for computing a posteriori error bounds for piecewise linear nonconforming approximate solution of elliptic equations. The upper error estimator is a quadratic function of free parameters. Optimal error bounds are obtained by solving a quadratic minimization problem. The feature of the method is that error estimates do not require the high regularity for the exact solution of the original problem.
