Variational problems with gradient constraints: $A priori$ and $a posteriori$ error identities

Harbir Antil, Sören Bartels, Alex Kaltenbach +1

In this paper, on the basis of a (Fenchel) duality theory on the continuous level, we derive an $a posteriori$ error identity for arbitrary conforming approximations of a…

Exact a posteriori error control for variational problems via convex duality and explicit flux reconstruction

Sören Bartels, Alex Kaltenbach

A posteriori error estimates are an important tool to bound discretization errors in terms of computable quantities avoiding regularity conditions that are often difficult to estab…
