A Rigidity Theorem for Flat Graph Hypersurfaces of Variable-Returns-to-Scale Cobb--Douglas Production Functions
Bang-Yen Chen, Sharief Deshmukh, Nasser Bin Turki +2
We study graph hypersurfaces associated with higher-dimensional () Cobb--Douglas production functions with variable returns to scale. We prove a rigidity theorem showing that…
An algorithm to estimate the vertices of a tetrahedron from uniform random points inside
Alina-Daniela Vîlcu, Gabriel-Eduard Vîlcu
In this paper, we give an algorithm to infer the positions of the vertices of an unknown tetrahedron, given a sample of points which are uniformly distributed within the tetrahedro…
Some characterizations of the quasi-sum production models with proportional marginal rate of substitution
Alina Daniela Vîlcu, Gabriel Eduard Vîlcu
In this note we classify quasi-sum production functions with constant elasticity of production with respect to any factor of production and with proportional marginal rate of subst…
On the elements of the Earth's ellipsoid of inertia
Alina-Daniela Vîlcu
By using the data for the known geopotential models by means of artificial satellite, the central moments of inertia of the Earth are determined. For this purpose, it was used the…
