Abstract: | Summary. We develop the a posteriori error analysis for the RFB method, applied to the linear advection-diffusion problem: the numerical
error, measured in suitable norms, is estimated in terms of the numerical residual. The robustness is investiged, in the sense
that we prove uniform equivalence between a norm of the numerical residual and a particular norm of the error.
