Invariant submanifolds of contact $(kappa,mu)$-manifolds

open access: yes, 2008
Invariant submanifolds of contact (, )-manifolds are studied. Our main result is that any invariant submanifold of a non-Sasakian contact (, )-manifold is always totally geodesic and, conversely, every totally geodesic submanifold of a non-Sasakian ...

Characterizations of pseudo-umbilical submanifolds of locally product Riemannian manifolds

open access: yes, 2023
Compared to totally umbilical submanifolds, studies on pseudo-umbilical submanifolds are quite limited. In this paper, pseudo-umbilical submanifolds of locally product Riemannian manifolds are studied.

On invariant submanifolds of lorentzian para-sasakian manifolds

open access: yes, 2009
We consider semiparallel and 2-semiparallel invariant submanifolds of Lorentzian para-Sasakian manifolds. We show that these submanifolds are totally geodesic.
