This is an informal **reading seminar on noncommutative geometry** and related topics organized by the group of master students, PhD students, postdocs and staff working on topics related to noncommutative geometry in Nijmegen. It forms a platform where we share with each other our ideas, projects, problems, papers, etc.

We meet on Tuesday afternoons (15:30-16:30). The theme of the coming semester is **quantum fields**.
