This paper is motivated by the asymptotic stabilization of abstract SPDEs linear type. As a first step, it proposes an contribution to exact controllability (in general Lp-sense, p>1) class SDEs with time-invariant rank control coefficient in diffusion term. From this point view, our generalizes some results Wang et al. (2017) where full and null were considered. Necessary conditions sufficient...
