Khovanov skein lasagna modules and exotica

SEMINARS: GAUGE THEORY AND TOPOLOGY

When: October 11, 2024
3:00 pm - 4:00 pm
Where: Science Center 507
Address: 1 Oxford Street, Cambridge, MA 02138, United States
Speaker: Mike Willis (Texas A&M)

The Khovanov skein lasagna module S(X;L) is a smooth invariant of a 4-manifold X with link L in its boundary. In this talk I will outline the construction of Khovanov skein lasagna modules, as well as new computations and applications including the detection of some exotic 4-manifolds. This work is joint with Qiuyu Ren.
