These processes are implicitly related to the possible arrow of time. The purpose of this article is to address these questions through the model ETH developed by Professor J. Fröhlich and his team at the Zurich. It will be noted that his model is not unrelated to the communications already published within the framework of the “Lîla-Entropie Project”, especially through the ordering of nested systems.}}
