On some geometric properties of quasi-product production models
Haila Alodan, Bang-Yen Chen, Sharief Deshmukh +1
In this article we obtain classification results on the quasi-product production functions in terms of the geometry of their associated graph hypersurfaces, generalizing in a new s…
Inequalities for generalized normalized -Casorati curvatures of slant submanifolds in quaternionic space forms
Jaewon Lee, Gabriel-Eduard Vîlcu
In this paper we prove two sharp inequalities involving the normalized scalar curvature and the generalized normalized -Casorati curvatures for slant submanifolds in quaternioni…
Geometric classifications of homogeneous production functions
Bang-Yen Chen, Gabriel Eduard Vilcu
In this paper, we completely classify homogeneous production functions with an arbitrary number of inputs whose production hypersurfaces are flat. As an immediate consequence, we o…
Ruled CR-submanifolds of locally conformal Kähler manifolds
Gabriel Eduard Vilcu
The purpose of this paper is to study the canonical totally real foliations of CR-submanifolds in a locally conformal Kähler manifold.
Curvature properties of pseudo-sphere bundles over paraquaternionic manifolds
Gabriel Eduard Vilcu, Rodica Cristina Voicu
In this paper we obtain several curvature properties of the twistor and reflector spaces of a paraquaternionic Kähler manifold and prove the existence of both positive and negative…
3-submersions from QR-hypersurfaces of quaternionic Kaehler manifolds
Gabriel Eduard Vilcu
In this paper we study 3-submersions from a QR-hypersurface of a quaternionic Kaehler manifold onto an almost quaternionic hermitian manifold. We also prove the non-existence of qu…
Riemannian submersions from almost contact metric manifolds
Stere Ianus, Adrian Mihai Ionescu, Raluca Mocanu +1
In this paper we obtain the structure equation of a contact-complex Riemannian submersion and give some applications of this equation in the study of almost cosymplectic manifolds…
Paraquaternionic CR-submanifolds of paraquaternionic Kahler manifolds and semi-Riemannian submersions
Stere Ianus, Stefano Marchiafava, Gabriel Eduard Vilcu
In this paper we introduce paraquaternionic CR-submanifolds of almost paraquaternionic hermitian manifolds and state some basic results on their differential geometry. We also stud…
Some constructions of almost para-hyperhermitian structures on manifolds and tangent bundles
Stere Ianus, Gabriel Eduard Vilcu
In this paper we give some examples of almost para-hyperhermitian structures on the tangent bundle of an almost product manifold, on the product manifold , where…
