Nearly Carbon Neutral Geometric Topology

Nearly Carbon Neutral Geometric Topology Conference: June 1-14, 2020

To our participants: Thank you for speaking, organizing, attending office hours and other live events, watching talks, commenting, and otherwise participating in NCNGT! Some final information: The website and talks will be up indefinitely (though speakers of course have the power to delete their videos from youtube should they choose), but the comment section will only be open for 1 more week, until Friday, June 19.
 We would love to hear your thoughts about this conference- what about the format did and didn't work, what we should change or keep the same in a future iteration- please consider filling out this feedback form!  Thank you for being part of this experiment with us- we learned a lot, both mathematically and otherwise, and hope you did too.-Allison and Martin (aka the organizers)


Notes from the joint 'Floer theory and low-dimensional topology', 'Investigating the L-space conjecture', and 'Knots, surfaces, and 4-manifolds' problem session are now available here.


Welcome! We're organizing a nearly carbon neutral conference featuring early career mathematicians in geometric topology.  Much of our inspiration (and practical knowledge!) comes from this white paper and practical guide by Ken Hiltner, a professor of environmental humanities at UCSB. We are greatly indebted to his work.

How it works:


In our experience, one of the most valuable aspects of the conference experience, especially for graduate students, is meeting other people interested in the same ideas. To facilitate this in our online setting, we encourage all participants to briefly introduce themselves here  and say a little bit about their mathematical interests.


We are primarily asychronous, so you can watch our pre-recorded talks whenever you like during the conference! This talks page is the central reference for all our talks. Clicking on the title of a mini-session will take you to its page. These currently just have titles and abstracts and as of Monday will also have videos. In addition, each of these pages has a comment sections which the speakers and organizers will be checking regularly, and which will serve as the central discussion/ questions location for the conference. Commenting is restricted to registered users, though they can be viewed by anyone.

Live events:

We have a variety of live events scheduled (see here for a calendar and listing by group), all of which will be run via Zoom, and are open only to registered participants.

Office hours, hosted by our speakers, are intended for graduate students to get face time with the speakers and dig into some of the details of their talks. If you are not a graduate student, you are welcome to attend these office hours, as long as you give priority to any students who are present. We also encourage all conference attendees to reach out to other participants to discuss research and learn new things.
