Abstract : In this paper, we prove that if every totally real bisectional curvature of an $n(\geqq 3)$-dimensional complete K\"ahler submanifold of a complex projective space of constant holomorphic sectional curvature $c$ is greater than $\frac{c}{6n(n+1)}(3n^2 + 2n-2),$ then it is totally geodesic and compact.
Keywords : Kahler manifold, sectional curvature, holomorphic sectional curvature, totally real bisectional curvature, totally
