Thompson's Groups, Annular Links, and Tangles

Louisa Liles ⟨lml2tb@virginia.edu⟩

Abstract:

Vaughan Jones showed how to associate links in the 3-sphere to elements of Thompson’s group F and proved that F gives rise to all link types. This talk will introduce Jones’s construction and discuss two recent extensions– the first is a method of building annular links from Thompson’s group T, which contains F as a subgroup, and the second is a method of building (n,n)-tangles, which give rise to an action of F on Khovanov’s chain complexes. This talk includes joint work with Slava Kruskhal and Yangxiao Luo.
