Abstract:
Recently, based on the Prage-Synge identity, a posteriori error estimator for finite element
approximations to the diffusion equation has been developed with the reliability constant to be one.
In this talk, I will talk about its generalization: error estimation based on the gap between
approximations of primal and dual problems and the localization of these estimators.
Generalization of the idea to the a posteriori error estimation of the reduced basis method will also be discussed.
