## Blockage hydrodynamics of one-dimensional driven conservative systems.(English)Zbl 1079.60076

Author’s abstract: We consider an arbitrary one-dimensional conservative particle system with finite-range interactions and finite site capacity, governed on the hydrodynamic scale by a scalar conservation law with Lipshitz-continuous flux $$h$$. A finite-size perturbation restricts the local current to some maximum value $$\varphi$$. We show that the perturbed hydrodynamic behaviour is entirely determined by $$\varphi$$ if $$\inf (h;\varphi)$$ is first non-decreasing and then non-increasing, which we believe is a necessary condition.
