New Developments in Four Dimensions

June 13–17, 2022 at the University of Victoria, BC, Canada


This conference will bring together experts in various aspects of four-dimensional topology. Themes include diffeomorphism groups of four-manifolds, construction and detection of exotic four-manifolds, and trisections of four-manifolds. In addition to standard plenary talks, we will have a lightning talk session open to submissions from all participants.

This conference is anticipated to occur in-person at the University of Victoria. A limited number of talks will be over Zoom, with most speakers presenting in-person.

Registration space for this conference is limited. To apply to participate in this conference, please fill out the application form by April 10th.
