Study group: quasiisometries and cohomologies of nilpotent groups
This is the webpage of the reading seminars on Antonelli and Young's work on ergodic quasiisometries and nilpotent groups.
The study group occurs on some Fridays of the Fall semester 2026 in the Salle Visio of M2 building.
Here you find
the paper of Antonelli and Young that we aim to understand. (published in Math. Ann.)
Please consult arXiv v3 from July 18.
