Geometry/Topology Seminar

Virtual Event

UNUSUAL TIME: 6pm - 7pm, Zoom
Featured Speaker
: Hokuto Konno (University of Tokyo)

Title: Floer K-theory for knots.

This talk is based on joint work with Jin Miyazawa and Masaki Taniguchi where we established a version of Seiberg-Witten Floer K-theory for knots. This framework is used to prove a version of “10/8-inequality for knots”, which effectively extracts difference between topological and smooth categories in knot theory. I will explain concrete applications including stabilizing numbers and relative genus bounds, as well as how we constructed this framework.

Zoom info available upon request.

Seminar Covid Statement
A notice to non-MIT seminar participants: at this time, not all seminars are open to the general public, and access to the MIT campus is highly regulated. Please check the seminar webpage or with the event organizer and confirm whether the seminar you'd like to attend is open to non-MIT (i.e. without CovidPass) attendees.
Some seminars may offer a Zoom option for off-campus participants.
To access MIT buildings for a math seminar without MIT's CovidPass, you must be invited via a Tim Ticket ahead of time. There are no exceptions; please make sure to plan accordingly before coming to campus. To be able to activate the Tim Ticket, the attendee will need to submit an attestation about vaccination and health status and provide contact info.
