## Abstract We develop the energy norm __a posteriori__ error analysis of exactly divergenceโ€free discontinuous RT~__k__~/__Q__~__k__~ Galerkin methods for the incompressible Navierโ€“Stokes equations with small data. We derive upper and local lower bounds for the velocityโ€“pressure error measured in
