Alternating with the Global Noncommutative Geometry Seminar (European node, organized in the even week numbers) we will also have a **local** version in Nijmegen (organized in the **odd week** numbers). It will be an informal 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 and its surroundings. It forms a platform where we share with each other our ideas, projects, problems, papers, etc.
