A central limit theorem for the modified massive arratia flow

Abstract:
The Modified Massive Arratia Flow is a model of infinitely many sticky
Brownian particles where the diffusion scaled proportionally to the aggregate
mass of the particles. The model was introduced by Konarvovskyi and later studied
by Konarovskyi and Renesse who showed that the diffusive behaviour of the model
is governed locally by the quadratic Wasserstein distance. In this talk we present
a central limit theorem for the occupation measure of the process in the case of
countably many starting points. A central ingredient of the proof is quantitative
decorrelation estimates in terms of the alpha-mixing coefficient for which we present
explicit non-standard coupling constructions.
Joint work with Vitalii Konaroskyi (Bielefeld) and Andrey Dorogovtsev (Kyiv).
