Aggregation equations with gradient potential as Radon measure and initial data in Besov‐Morrey spaces

In this work, we present conditions to obtain a global‐in‐time existence of solutions to a class of nonlinear viscous transport equations describing aggregation phenomena in biology with sufficiently small initial data in Besov‐Morrey spaces and gradient potential as a Radon measure. We also study the self‐similarity and asymptotic stability of solutions at large times.
