Certain Class Of Contact Cr-Submanifolds Of A Sasakian Space Form

In this paper we investigate (n + 1)(n >= 3)-dimensional contact CR-submanifolds M of (n-1) contact CR-dimension in a complete simply connected Sasakian space form of constant phi-holomorphic sectional curvature c not equal -3which satisfy the condition h(FX, Y)+h(X, FY) = 0 for any vector fields X, Y tangent to M, where h and F denote the second fundamental form and a skew-symmetric endomorphism (defined by (2.3)) acting on tangent space of M, respectively.
