Abstract
First we introduce the notion of commuting and parallel Ricci tensor for real hypersurfaces in the complex quadric \(Q^m = SO_{m+2}/SO_2SO_m\). Then, according to the \(\mathfrak {A}\)-principal or the \(\mathfrak {A}\)-isotropic unit normal vector field N, respectively, we give a classification of real hypersurfaces in \(Q^m = SO_{m+2}/SO_2SO_m\) with Reeb parallel Ricci tensor.
