Intrinsic Finite-Step Characterizations of Discrete General Helices
Dae Won Yoon, Chul Woo Lee, Jae won Lee
We study polygonal general helices in Euclidean three-space using the turning and signed torsion angles of the discrete Frenet frame. For helices whose axis is not orthogonal to th…
Partially Totally Real Submanifolds of Sasakian Manifolds
Chul Woo Lee, Jae Won Lee
Partially totally real (PTR) submanifolds were introduced in Kähler geometry by distinguishing a totally real distribution and leaving its orthogonal complement unrestricted. In th…
The Faraday Form of Conformal Products: Weyl Curvature and Four-Dimensional Einstein Rigidity
Jae Won Lee
Let carry a conformal product structure whose adapted Weyl connection preserves orthogonal distributions of ranks . We express the Faraday form directly…
Constancy of holomorphic scetional curvature in generalized manifolds
Jae Won Lee, Dae Ho Jin
Tanno [6] provided an algebraic characterization in an almost Hermitian manifold to reduce to a space of constant holomorphic sectional curvature, which he later extended for the S…
