A discontinuous Galerkin method on kinetic flocking models

We study kinetic representations of flocking models. They arise from agent-based models for self-organized dynamics, such as Cucker-Smale and Motsch-Tadmor models. We prove flocking behavior for the kinetic descriptions of flocking systems, which indicates a concentration in velocity variable in infinite time. We propose a discontinuous Galerkin method to treat the asymptotic $δ$-singularity, and construct high order positive preserving scheme to solve kinetic flocking systems.
