Abstract This article studies the problem of L 2 stability and weak‐strong uniqueness of solutions of the incompressible Navier‐Stokes on the whole space \input amssym ${\Bbb S}^3$ constructed by Kato's approach in spaces coming from Littlewood‐Paley theory and using the L 1 smoothing effect for the heat flow. © 2011 Wiley Periodicals, Inc.
