On some geometric properties of quasi-product production models
Vilcu, Haila Alodan, Bang-Yen Chen, Sharief Deshmukh, Gabriel-Eduard . 2019
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 setting some recent results concerning basic production models. In particular, we obtain several results on the geometry of Spillman–Mitscherlich and transcendental production functions.
We aim to examine the influence of the existence of a nonzero eigenvector z of the de-Rham
operator G on a k-dimensional Riemannian manifold (Nk, g). If the vector z annihilates the de-Rham…
The Fischer-Marsden conjecture asserts that an n-dimensional compact manifold admitting a nontrivial solution of the so-called Fischer-Marsden differential equation is necessarily an Einstein…
We use a nontrivial concircular vector field u on the unit sphere Sn+1 in studying
geometry of its hypersurfaces. An orientable hypersurface M of the unit sphere Sn+1
naturally…
