Similarity:

In the present paper we investigate a contact metric manifold satisfying (C) ( ¯ γ ˙ R ) ( · , γ ˙ ) γ ˙ = 0 for any ¯ -geodesic γ , where ¯ is the Tanaka connection. We classify the 3-dimensional contact metric manifolds satisfying (C) for any ¯ -geodesic γ . Also, we prove a structure theorem for a contact metric manifold with ξ belonging to the k -nullity distribution and satisfying (C) for any ¯ -geodesic γ .

Deformations of structures, embedding of a Riemannian manifold in a Kählerian one and geometric antigravitation

Tubular neighborhoods play an important role in modern differential topology. The main aim of the paper is to apply these constructions to geometry of structures on Riemannian manifolds. Deformations of tensor structures on a normal tubular neighborhood of a submanifold in a Riemannian manifold are considered in section 1. In section 2, this approach is used to obtain a Kählerian structure on the corresponding normal tubular neighborhood of the null section in the tangent bundle TM of...
