Guaranteed, locally space-time efficient, and polynomial-degree robust a posteriori error estimates for high-order discretizations of parabolic problems

Alexandre Ern, Iain Smears, Martin Vohralík

We consider the a posteriori error analysis of approximations of parabolic problems based on arbitrarily high-order conforming Galerkin spatial discretizations and arbitrarily high…

Discrete $p$ -robust $H (div)$ -liftings and a posteriori estimates for elliptic problems with $H^{- 1}$ source terms

Alexandre Ern, Iain Smears, Martin Vohralík

We establish the existence of liftings into discrete subspaces of $H (div)$ of piecewise polynomial data on locally refined simplicial partitions of polygonal/poly…
