abstract = {<p style="text-align: justify;">In this paper, we derive rigorously a non-local cross-diffusion system from an interacting stochastic many-particle system in the whole space.
The convergence is proved in the sense of probability by introducing an intermediate particle system with a mollified interaction potential, where the mollification is of algebraic scaling. The main idea of the proof is to study the time
evolution of a stopped process and obtain a Grönwall type estimate by using
Taylor’s expansion around the limiting stochastic process.</p>},
