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…

Two series of polyhedral fundamental domains for Lorentz bi-quotients
Nasser Bin Turki, Anna Pratoussevitch
The main aim of this paper is to give two infinite series of examples of Lorentz space forms that can be obtained from Lorentz polyhedra by identification of faces. These Lorentz s…
