In this paper we determine some properties of pseudo-projective curvature
tensor denoted by ?P on some Riemannian manifolds, especially on generalized
quasi Einstein manifolds in the sense of Chaki. Firstly, we consider a
pseudo-projectively Ricci semisymmetric generalized quasi Einstein manifold.
After that, we study pseudo-projective flatness of this manifold. Moreover,
we construct a non-trivial example for a generalized quasi Einstein manifold
to prove the existence.
