Abstract: Recently. a new class of error indicators and estimators for the finite element method has been introduced which is particularly easy to implement into existing finite element codes. This paper proves that the new indicators are equivalent to those analyzed earlier by Babuska, thus showing that the rigorous mathematical results for the well-known jump indicator apply also for the new ones.
