“…In addition, in this setting, one can study consistency with hydrodynamic limits and non-regularising kinetic PDEs with general initial data. The L 2 -framework is general enough to treat a large class of models [16,14,15], and it can provide sharp estimates for some specific models [7,1,3,2,6]. Precise algebraic features of the framework and estimates with respect to the parameters defining the dynamics were studied in [11].…”
