### Abstract

In a previous paper (referred to here as paper I) we showed that the Einstein equation is linearization stable when a Robertson-Walker model of curvature K = O is considered. For that purpose, a slightly different definition of linearization stability was introduced. In this paper we show that in case the curvature K is equal to 1 the Einstein equation G(g) = XT is not linearization stable at the Robertson-Walker metric. © 1999 American Institute of Physics.
