Fundamental properties of these submanifolds are investigated such as integrability of distributions, totally umbilical semi-invariant submanifold. Finally, necessary and sufficient conditions are given on a semi-invariant submanifold of a Riemannian product manifold to be a locally Riemannian manifold. © Balkan Society of Geometers.eninfo:eu-repo/semantics/closedAccessConstant sectional curved manifoldMixed geodesic submanifoldRiemannian product manifoldTotally umbilical submanifoldArticle81911002-s2.0-17844372706Q3
