Geometric characterization of totally geodesic SODE submanifolds

open access: yes, 2019
Investigating the geometry of the tangent bundle (TMM) over a smooth manifold M is one of the most significant fields of modern differential geometry and has remarkable applications in various problems specifically in the theory of physical fields.

Totally geodesic submanifolds of regular Sasakian manifolds

open access: yesOsaka Journal of Mathematics, 2012
The main result of this paper finds a correspondence between certain types of totally geodesic submanifolds of a homogeneous Sasakian manifold (necessarily regular) and submanifolds of its Hermitian symmetric base space (via the Boothby-Wang fibration).

Positively curved totally real minimal submanifolds immersed in a complex projective space

open access: yes, 1976
A sufficient condition for a complete totally real minimal submanifold immersed in a complex projective space to be totally geodesic is given in terms of sectional curvature.

Invariant Totally Geodesic Unit Vector Fields on Three-Dimensional Lie Groups

open access: yes, 2007
We give a complete list of left-invariant unit vector fields on three-dimensional Lie groups equipped with a left-invariant metric that generate a totally geodesic submanifold in the unit tangent bundle of a group equipped with the Sasaki metric.

On Ricci curvature of totally real submanifolds in a quaternion projective space [PDF]

open access: yes, 2002
summary:Let $M^n$ be a Riemannian $n$-manifold. Denote by $S(p)$ and $\overline{\operatorname{Ric}}(p)$ the Ricci tensor and the maximum Ricci curvature on $M^n$, respectively.

Symplectomorphic codimension 1 totally geodesic submanifolds

open access: yesDifferential Geometry and its Applications, 1995
We show that the coisotropic totally geodesic properly embedded submanifolds of codimension 1 of a simply connected complete Kähler manifold of non-positive sectional curvature are symplectically linearizable. First we show that such a submanifold is foliated by totally geodesic complex leaves transversal to an isometric flow, hence, by a result of E ...
