Pradip Majhi, Y. Matsuda, U. C. De

• The object of the present paper is to study projective curvature tensor in K-contact manifolds. Projectively birecurrent K-contact manifold have been studied. K-contact manifold satisfying P.R = O, R(X, ~).P = P(X, ~).R and P.S = O are also considered. Finally, we study 4>-projectively symmetric K-contact manifolds. It is shown that in ali the cases the K-contact manifold becomes Sasakian
