The present paper deals with weakly symmetric and weakly Ricci-symmetric
almost r-para contact manifolds of LP-Sasakian type and Kenmotsu type. We
obtain necessary conditions in order that an almost r-para contact manifolds
of LP-Sasakian and of Kenmotsu type be weakly symmetric and weakly Riccisymmetric, respectively .
Keywords and Phrases : Almost r-para contact manifold , weakly symmetric
manifold, weakly Ricci-symmetric manifold
