This research aims to establish a quantitative mean-field limit for particle systems interacting through non-attractive singular kernels.
Analyzed particle systems with inertialess binary interaction using Wasserstein distances.
Controlled initial configurations through minimal distance and singular sums of particle distances.
Extended results on chaos propagation by relaxing the conditions on interaction signs.
Proved propagation of chaos for alpha < (d-1)/2 for d ≥ 3.
Demonstrated chaos propagation for alpha < 1/3 for d = 2.
Extended previous results that required alpha < (d-2)/2 with no sign assumptions.

Höfer et al. (2026) studied this question.
