Addendum to the paper “Real hypersurfaces in complex two-plane Grassmannians with -invariant Ricci tensor”.

Abstract: In this paper, we introduce some notions of invariancy for the Ricci tensor on real hypersurfaces in complex two-plane Grassmannians , namely, -invariant and invariant Ricci tensor. Using these notions, we give non-existence theorem and characterization for the special case among the real hypersurfaces of Type in , respectively. Here the distribution is defined by where and .
