“…Hydrodynamic limits towards macroscopic limits have been derived in 87,108 . Other corrections of (5.55) that smooth the momentum term have been studied in 36,86 Regarding the aggregation equation (5.3), there is a huge literature, see 35,44,54,167,166,205,206 and related references. Indeed, similar estimates to those in Theorem 5.15 have been proved for such family of gradient-flow systems.…”
