J. Weisz, A-POSTERIORI ERROR ESTIMATE OF APPROXIMATE SOLUTIONS TO A SPECIAL NONLINEAR ELLIPTIC BOUNDARY-VALUE PROBLEM, Zeitschrift fur angewandte Mathematik und Mechanik, 75(1), 1995, pp. 79-81
The paper deals with the construction of an a-posteriori error estimat
e of the approximate solution to a special nonlinear elliptic boundary
Value problem with the Dirichlet boundary condition. The convergence
of the presented error estimate to the true error is proved.
