Non-Commutative Geometry and Cyclic Homology 2020

Conference at Mathematisches Forschungsinstitut Oberwolfach, June 28-July 4

Practical Information

Due to the Corona restriction, the conference is organized as a hybrid on-site and video conference workshop. All talks are broadcast via zoom and most will also be recorded. If you are interested in participation, please contact Ryszard Nest or Thomas Schick for access information. To make the life participation possible for the majority of participants spread over the world, most activity will be concentrated in the afternoons.

Noncommutative geometry applies ideas from geometry to mathematical structures determined by noncommuting variables. Within mathematics, it is a highly interdisciplinary subject drawing ideas and methods from many areas of mathematics and also from physics. Natural questions involving noncommuting variables arise in abundance in many parts of mathematics. On the basis of ideas and methods from algebraic and differential topology and Riemannian geometry, as well as from the theory of operator algebras and from homological algebra, an extensive machinery has been developed which permits the formulation and investigation of the geometric properties of noncommutative structures. This includes in particular K-theory and cyclic homology. Areas of intense research in recent years are related to topics such as index theory, quantum groups and Hopf algebras, the Novikov and Baum-Connes conjectures as well as to the study of specific questions in other fields such as number theory, modular forms, topological dynamical system, renormalization theory.


Activities commence Monday, June 29 in the morning. Most of the activity is scheduled for the afternoon. Currently, we plan to have on-site talks Friday morning, the scientific activity ending Friday at lunchtime CET.
