Totally real submanifolds of generalized Hopf manifolds
Le Matematiche, 1987 We classify totally geodesic totally-real submanifolds of generalized Hopf manifolds, provided the normal connection is flat.

The feasibility principle in community ecology
Oikos, EarlyView.The structure and function of ecological communities emerge from interactions among populations within specific environmental contexts. Yet we still lack general principles that explain how communities assemble, which patterns we should expect, and when transitions occur across diverse settings.

A note on a totally umbilical proper slant submanifold of a nearly Kaehler manifold
Kuwait Journal of Science, 2013 In this paper, we study totally umbilical proper slant submanifolds of a nearly Kaehler manifold. We prove that every totally umbilical proper slant submanifold of a nearly Kaehler manifold is totally geodesic.

Riemannian and Sub-Riemannian geodesic flows
, 2015 In the present paper we show that the geodesic flows of a sub-Riemannian metric and that of a Riemannian extension commute if and only if the extended metric is parallel with respect to a certain connection. This helps us to describe the geodesic flow of

Polymer Composites, EarlyView.Manufacturability‐aware multi‐objective screening of Type IV filament‐wound composite pressure‐vessel cylindrical sections toward lightweight and high‐strength designs. ABSTRACT A manufacturability‐aware preliminary screening framework is proposed for the straight cylindrical section of filament‐wound Type IV composite pressure vessels.

Characterization of totally geodesic K\"{a}hler immersions
Hokkaido Mathematical Journal, 2002 In his paper [Nagoya Math. J. 60, 180-188 (1976; Zbl 0305.53046)], \textit{K. Nomizu} characterized totally geodesic complex projective spaces among Kähler submanifolds of a complex projective space using an extrinsic property of geodesics. The introduction of the paper presents a review of results on the characterization of submanifolds by the ...

Totally geodesic submanifolds of Damek–Ricci spaces
Revista Matemática Iberoamericana, 2020 We classify totally geodesic submanifolds of Damek–Ricci spaces and show that they are either subgroups (“smaller” Damek–Ricci spaces) or isometric to rank-one symmetric spaces of negative curvature.

Main‐chain polyfullerenes: Taking fullerene to the next dimension
Polymer International, EarlyView.This short review appraises main‐chain polyfullerenes. Their slow development over 30 years has suddenly boomed with a rapid growth due to exciting developments in solar energy. Abstract This mini‐review gives an overview of the development, chemistry, properties and applications of main‐chain polyfullerenes.

Geometrical Analysis on Submanifolds in Riemannian Manifolds Attached with Silver Structure
AxiomsIn this paper, we analyze a silver Riemannian structure on a Riemannian manifold. We compute some fundamental properties of the induced structure on submanifolds immersed in a silver Riemannian manifold and also obtain some results for induced structures

Hypersurfaces of Projective β –Changes [PDF]
Memoirs of the Scientific Sections of the Romanian Academy, 2011 In 1984 C. Shibata investigated the theory of a change which is called a β -change of Finsler metric [10]. On the other hand, in 1985 a systematic study of geometry of hypersurfaces in Finsler spaces was given by M. Matsumoto [6].
