A robust a posteriori error estimator for the Oseen problem
Muhammad Afzal, Naveed Ahmed, Volker John
A residual-based a posteriori error estimator is proposed for the incompressible Oseen problem in the convection-dominated regime. The SUPG/PSPG/grad-div stabilized finite element…

Error analysis of BDF schemes for the evolutionary incompressible Navier--Stokes equations
Bosco GarcÃa-Archilla, V. John, Julia Novo
Error bounds for fully discrete schemes for the evolutionary incompressible Navier--Stokes equations are derived in this paper. For the time integration we apply BDF- methods, $…
