Abstract

We consider a hydrodynamic model of flocking-type with all-to-all inter- action kernel in one-space dimension and establish global existence of entropy weak solutions to the Cauchy problem for any BV initial data that has finite total mass con- fined in a bounded interval and initial density uniformly positive therein. In addition, under a suitable condition on the initial data, we show that entropy weak solutions admit time-asymptotic flocking.
