Title THE RELATIONSHIP BETWEEN RICCI CURVATURE AND SQUARED MEAN CURVATURE OF SUBMANIFOLDS OF A CONFORMALLY SASAKIAN SPACE FORM Type of Research Presentation Keywords Ricci curvature, squared mean curvature, conformally Sasakian space form Abstract We obtain a basic inequality involving the Ricci cur- vature and the squared mean curvature of a submanifold of a con- formally Sasakian space form and consider the hypotheses of sat- isfying the equality.
