A Posteriori Error Estimates without Generic Constants
Abstract: Recently the equilibrated residual method has attracted the interest since it provides a posteriori estimates without a generic constant in the main term. It may be traced back to Prager and Synge and is found with different names. We boil it down in three steps to obtain a cheap method. It also becomes more transparent which makes an an extension to other problems easier. We apply the idea to edge elements that are appropriate for treating Maxwell's equations. The difference to the scalar case is substantial since different exact sequences are involved in the construction. In particular, terms wih respect to geometric objects of different dimension have to be equilibrated.
