Abstract. We present a systematic approach to regularity theory of the multi-dimensional Euler alignment systems with topological diffusion introduced in [27]. While these systems exhibit flocking behavior emerging from purely local communication, bearing direct relevance to empirical field studies, global and even local well-posedness has proved to be a major challenge in multi-dimensional settings due to the presence of topological effects. In this paper we reveal two important classes of…
