A Stochastic production planning problem
Elena Cristina Canepa, Dragos-Patru Covei, Traian A. Pirvu
Stochastic production planning problems were studied in several works; the model with one production good was discussed in [3]. The extension to several economic goods is not a tri…
An elliptic partial differential equation and its application
Dragos-Patru Covei, Traian A. Pirvu
This paper deals with the following elliptic equation \begin{equation*} -2σ^{2}Δz+\left\| \nabla z\right\| ^{2}+4αz=4\left\| x\right\| ^{2}\text{ for }x\in \mathbb{R}^{N}\text{, (}…
An elliptic partial differential equations system and its application
Dragos-Patru Covei, Traian A. Pirvu
This paper deals with the existence of solutions for an elliptic system of partial differential equations. The solution method is based on the sub- and super-solutions approach. An…
