Local Central Limit Theorem for Multi-Group Curie-Weiss Models
arXiv:2012.08349 · doi:10.1007/s10959-021-01122-4
Abstract
We define a multi-group version of the mean-field spin model, also called Curie-Weiss model. It is known that, in the high temperature regime of this model, a central limit theorem holds for the vector of suitably scaled group magnetisations, that is the sum of spins belonging to each group. In this article, we prove a local central limit theorem for the group magnetisations in the high temperature regime.
