[Topology.beta] Today at 11: AG with Yuka Kotorii

[Rot, T.O. (Thomas)]

Dear all,

Today at 11 we have the AG with a guest of Senja. Hope to see you there!

AG: 19-03-2024: 11:00 in Maryam: Yuka Kotorii <https://wpi-skcm2.hiroshima-u.ac.jp/people/yuka-kotorii/> (Hiroshima): Homotopy theories of colored links and spatial graphs

Abstract: Two links are called link-homotopic if they are transformed to each other by a sequence of self-crossing changes and ambient isotopies. The notion of link-homotopy is generalized to spatial graphs and it is called component-homotopy. The link-homotopy classes were classified by Habegger and Lin through the classification of the link-homotopy classes of string links. In this talk, we classify colored string links up to colored link-homotopy by using the Habegger-Lin theory. Moreover, we classify colored links and spatial graphs up to colored link-homotopy and component-homotopy respectively. This research is joint work with Atsuhiko Mizusawa.

Best,
Thomas
