Abstract : In general, the objective of a computational solution of a practical problem is to obtain an acceptably accurate and reliable prediction of the behavior of the physical phenomena under study. For this computation should produce not only an approximate numerical solution but also some reliable information about its accuracy. This survey is intended to give an overview of some of the recent results that have become available about reliable, computable error estimators for finite element solutions as they exist in the design of adaptive solution procedures both in the linear as well as the nonlinear case. By necessity, the discussion had to be kept on a descriptive level and for all mathematical details we need to refer to the cited literature.
