(Conformally) semisymmetric spaces and special semisymmetric Weyl tensors

Curvature properties of Gödel metric

“…Semi-Riemannian warped products having parallel Weyl conformal curvature tensor were investigated in [47]. We also mention that, recently, conformally semisymmetric manifolds and special semisymmetric Weyl conformal tensors are studied in [48]. Another important subclass of semisymmetric semi-Riemannian manifolds form manifolds satisfying…”
