A one-parameter family of totally umbilical hyperspheres in the nearly Kaehler 6-sphere

Jihong Bae, JeongHyeong Park, Kouei Sekigawa

We discuss two kinds of almost contact metric structures on a one-parameter family of totally umbilical hyperspheres in the nearly Kaehler unit 6-sphere.

A curvature identity on a 6-dimensional Riemannian Manifold and its applications

Yunhee Euh, JeongHyeong Park, Kouei Sekigawa

We derive a curvature identity that holds on any 6-dimensional Riemannian manifold, from the Chern-Gauss-Bonnet theorem for a 6-dimensional closed Riemannian manifold. We also intr…

Curvature identities on contact metric manifolds and their applications

JeongHyeong Park, Kouei Sekigawa, Won Min Shin

We study curvature identities on contact metric manifolds on the geometry of the corresponding almost Käehler cones, and we provide applications of the derived curvature identities…

A generalization of contact metric manifolds

J. H. Kim, J. H. Park, K. Sekigawa

We give a characterization of a contact metric manifold as a special almost contact metric manifold and discuss an almost contact metric manifold which is {a} natural generalizatio…

Orthogonal almost complex structures on the Riemannian products of even-dimensional round spheres

Yunhee Euh, Kouei Sekigawa

We discuss the integrability of orthogonal almost complex structures on Riemannian products of even-dimensional round spheres and give a partial answer to the question raised by E.…

Transplanting geometrical structures

Y. Euh, P. Gilkey, J. H. Park +1

We say that a germ G of a geometric structure can be transplanted into a manifold M if there is a suitable geometric structure on M which agrees with G on a neighborhood of some po…
