Simplicial volume and isolated, closed totally geodesic submanifolds of codimension one

open access: yes
We show that for any closed Riemannian manifold with dimension at least two and with nonpositive curvature, if it admits an isolated, closed totally geodesic submanifold of codimension one, then its simplicial volume is positive. As a direct corollary of

On totally geodesic invariant submanifolds of an S-manifold

open access: yes, 2016
In [1] Blair, O.E.: 1970, J. Diff. Geom. 4, (155-167), S-manifolds, which reduce in a special case to Sasakian manifolds, we redefined. In this note, a condition for an invariant submanifold of codimension greater than 2 in a n S-manifold to be totally geodesic is obtained.
