Real hypersurfaces in complex two-plane Grassmannians with Reeb parallel Ricci tensor

In this paper we introduce a new notion of Reeb parallel Ricci tensor for real hypersurfaces in complex two-plane Grassmannians G2(Cm+2). Next we give a complete classification of Hopf real hypersurfaces in complex two-plane Grassmannians G2(Cm+2) with Reeb parallel Ricci tensor.
