---------------------------------------------------
Abstract seminario Chaumont-Frelet:
Beyond its intrinsic physical interest, the magnetostatic problem is
mathematically attractive as a model for PDEs involving the curl
differential operator. In this talk I will consider a posteriori error
estimators for finite element discretizations based on the idea of “flux
equilibration”. This technique is well-established in the H1 framework
where it leads to guaranteed error upper-bounds and
polynomial-degree-robust local lower-bounds. In the H(curl) framework,
however, the development of equilibration strategies is much more recent. I
will report on two new constructions of equilibrated estimators for the
magnetostatic problem. Reliability and efficiency of both estimators will
be discussed and illustrated by numerical examples.
This is a joint work with Martin Vohralik.
