Real hypersurfaces in the complex quadric with Reeb invariant Ricci tensor

We introduce the notion of Reeb invariant Ricci tensor for real hypersurfaces in the complex quadric Qm=SOm+2∕SOmSO2 . The Reeb invariant Ricci tensor implies that the unit normal vector field N becomes A-principal or A-isotropic. Then according to each case, we give a complete classification of real hypersurfaces in Qm=SOm+2∕SOmSO2 with Reeb invariant Ricci tensor.
