In recent times, there has been an increasing interest in studying swarming and flocking behavior of animals with mathematical tools. I will present kinetic models that are inspired by the so-called Vicsec model for the motion of "self propelled particles". A Boltzmann like equation based on the Vicsec model derived by Chaté et. al. In the talk I will discuss some mathematical problems related to this and a different, but similar, model: propagation of chaos and fluid limits.
The work is a collaboration with Eric Carlen and Pierre Degond.
