The College of Science in the Department of Mathematics discussed a master thesis titled (Projective Curvature Tensors and Curvature Inheritance Symmetry on C_9- Manifolds) for postgraduate student Humam Taha. The thesis focuses on C_9-manifolds on the associated G–structures (AGS-) space. Where The components of covariant derivative of its Riemannian curvature tensor R determine.
