摘要：

An algebra is said to be tau-tilting finite provided it has only a finite number of tau-rigid objects up to isomorphism. To each such algebra, we associate a category whose objects are the wide subcategories of its category of finite dimensional modules, and whose morphisms are indexed by support tau-tilting pairs.
