We study the aggregation equation $\rho_t + \nabla \cdot (\rho (-\nabla K \ast \rho)) = 0$ in $\Real^n$, a first-order nonlinear and non-local transport equation used to model swarming behaviour. The radial interaction potential is chosen $K$ to model both short-range repulsion and long-range attraction. We show global-well-posedness of solutions using the particle-trajectory method, a technique first used for the proving global existence and uniqueness of the Euler equation. Specifically, the interaction kernel is selected in order to calculate an analytic solution of density along particle trajectories and to make use of the well-developed theory of singular integral operators. We also show that solutions with a compactly supported radial...
