In this paper we study the H 1-stability for all positive time of the BDF2 scheme for the 2D Navier–Stokes equations. More precisely, we discretize in time using the backward differentiation formula (BDF2), and with the aid of the discrete Gronwall lemma and of the discrete uniform Gronwall lemma we prove that the numerical scheme admits this stability.
