Further we consider concircular curvature tensor satisfying some geometric conditions of an invariant submanifold of an LP-Sasakian manifold to be totally geodesic. In extension, we build an example of LP-Sasakian manifold to verify our main result totally geodesic.http://www.kjm-math.org/article_97091_d52712c3a0533f86645740d2df993eba.pdf
