Algebraic central limit theorems: A personal view on one of Wilhelm’s legacies

Abstract

Bringing forward the concept of convergence in moments from classical random variables to quantum random variables leads to what can be called algebraic central limit theorem for (classical and) quantum random variables. I reflect in a very personal way how such an idea is typical for the spirit of doing research in mathematics as I learned it in Wilhelm von Waldenfels’s research group in Heidelberg.
