Adaptive mesh refinement and a posteriori error estimation for the p- version of the finite element method. (English) Zbl 0564.65070

The authors consider the construction of reliable a posteriori error estimates and efficient adaptive processes for the finite element method. The error estimates and refinement strategies are based directly on the concept of hierarchical finite elements. Correction indicators and error estimators are introduced for indication where additional degrees of freedom will be most effective. Some adaptive strategies and solution procedures are given together with numerical examples.
