Noise Prevents Collapse of Vlasov‐Poisson Point Charges

F Delarue, F Flandoli, D Vincenzi - Communications on Pure …, 2014 - Wiley Online Library
We elucidate the effect of noise on the dynamics of N point charges in a Vlasov‐Poisson
model with a singular bounded interaction force. A too simple noise does not affect the …

Lagrangian coherent structures and inertial particle dynamics
