Low Dimensional Topology


If you have a conference you’d like to advertise in low dimensional topology, simply leave a comment below with the basic info (date, location, topic) and perhaps a link to the conference website. Comments for events that have already happened will be deleted periodically; there used to be a more professional-looking list of events ordered by date, but it wasn’t updated often enough so we’re going to try something cruder but automatic. More conference listings are available on the Topology Atlas, Jon McCammond’s home page, the AMS conference calendar, and the UTK geometry listserv.

If you submit a comment and it doesn’t appear due to need for “moderation”, contact Nathan Dunfield.


  1. Applications are open to participate in NCNGT 2021, a mixed (a)synchronous conference running online from June 14-25, 2021.

    NCNGT showcases the work of early career researchers in geometric topology. This year, we will have nine special sessions, each with pre-recorded talks, discussion via Discord, and live events like teas, office hours, and problem sessions.

    This year’s topic groups:
    Beyond the chalkboard: topology through outreach
    Dynamics and geometry of discrete subgroups of Lie groups
    Foliations, flows, and dynamics in 3-manifolds
    Recent techniques in Floer and Khovanov homology
    Hyperbolic manifolds
    Infinite type surfaces and big mapping class groups
    Knots and braids in dimensions 3 and 3.5
    Low-dimensional contact and symplectic topology
    Symmetric spaces and generalizations

    We will also have four live plenary talks, given by Jayadev Athreya (Washington), Ian Biringer (Boston College), Priyam Patel (Utah), and Arunima Ray (MPIM).

    Applications to participate are due Monday, June 7; we will notify applicants on a rolling basis. We also encourage anyone interested — but especially graduate students — to submit a “Postcard from a Geometric Topologist”.

    For more information, please see the conference website at http://www.ncngt.org or email the organizers at ncngt.organizers@gmail.com

  14. UNYTS 2022: 3rd Upstate New York Topology Seminar

    Syracuse University, October 22, 2022

    This is a one-day regional in-person topology conference focussing on algebraic and low-dimensional topology. There will be three plenary talks, given by Francesco Lin, Allison N. Miller, and Martina Rovelli, as well as parallel sessions. For these, we plan to have an open call for speakers, with preference given to early-career participants (students, postdocs, and tenure-track professors) and to regional speakers (from the broad region of New York State and nearby).

    We have applied for limited funding for accommodation with priority given to early career participants.

    Website and registration: https://clamille.github.io/UNYTS2022.html

    Important: To have an idea of the potential number of attendees, we would appreciate if you could register by September 1. The deadline for requesting to speak in the parallel sessions is September 1.
