Global in time stability and accuracy of IMEX-FEM data assimilation schemes for Navier–Stokes equations

We study numerical schemes for incompressible Navier–Stokes equations using IMEX temporal discretizations, finite element spatial discretizations, and equipped with continuous data assimilation (a technique recently developed by Azouani et al. (2014)). We analyze stability and accuracy of the propos...
