  The projective curvature tensor $P$ is invariant under a geodesic preserving
transformation on a semi-Riemannian manifold. It is well known that $P$ is not
a generalized curvature tensor and hence it possesses different geometric
properties than other generalized curvature tensors. The main object of the
present paper is to study some semisymmetric type and pseudosymmetric type
curvature restricted geometric structures due to projective curvature tensor.
The reduced pseudosymmetric type structures for various Walker type conditions
are deduced and the existence of Venzi space is ensured. It is shown that the
geometric structures formed by imposing projective operator on a (0,4)-tensor
is different from that for the corresponding (1,3)-tensor. Characterization of
various semisymmetric type and pseudosymmetric type curvature restricted
geometric structures due to projective curvature tensor is obtained on a
Riemannian and a semi-Riemannian manifold, and it is shown that some of them
reduce to Einstein manifold for the Riemann case. Finally to support our
theorems four suitable examples are presented.
