Abstract
We prove a uniqueness result of solutions for a system of PDEs of Monge–Kantorovich type arising in problems of mass transfer theory. The results are obtained under very mild regularity assumptions both on the reference set \({\Omega\subset \mathbb{R}^n}\), and on the (possibly asymmetric) norm defined in Ω. In the special case when Ω is endowed with the Euclidean metric, our results provide a complete description of the stationary solutions to the tray table problem in granular matter theory.
