In this paper, we consider a compact , connected and simply connected Kaehlerian manifold M of complex dimension n > 1 admitting a holomorphically projective vector field^2,3,4,6,8. The purpose of the paper is to obtain the integral formulas and inequalities in Kaehlerian manifold M without assuming the condition that the scalar curvature K of M is constant and to deduce a Theorem of K.Yano and H. Hiramatu¹² from our results.
