Abstract

In the present note, we study slant and hemislant submanifolds of an LP-cosymplectic manifold which are totally umbilical. We prove that every totally umbilical proper slant submanifold 𝑀 of an LP-cosymplectic manifold 𝑀 is either totally geodesic or if 𝑀 is not totally geodesic in 𝑀 then we derive a formula for slant angle of 𝑀 . Also, we obtain the integrability conditions of the distributions of a hemi-slant submanifold, and then we give a result on its classification.
