Title of the talk: Existence of solutions to one- dimensional hughes model for pedestrian evacuation

Annotation

We present two proofs of existence for solutions of the Hughes’ model describing the evacuation of a corridor by its two ends. The model takes the form of a discontinuous-flux scalar hyperbolic conservation law with a moving interface. One proof uses a Schauder fixed-point argument. The other one is obtained through constructing a many-particle Hughes’ model and analyzing its convergence with the help of BV_loc estimates.
