Abstract:

Vlasov equations can be formally derived from $N$-body dynamics in the mean-field limit. In some suitable singular limits, they may themselves converge to fluid dynamics equations. Motivated by this heuristic, we introduce natural scalings under which the incompressible Euler equations can be rigorously derived from $N$-body dynamics with repulsive Coulomb interaction. Our analysis is based on the modulated energy methods of Brenier and [Comm. Partial Differential Equations 25 (2000), pp. 737–754] Serfaty [Duke Math. J. 169 (2020), pp. 2887–2935].
