(NCNGT2021) On Khovanov Homology and Related Invariants, Part 2

This two-part talk is based on the my work with Carmen Caprau, Nicolle Gonzalez, Christine Ruey Shan Lee, Adam Lowrance, and Radmila Sazdanovic.

Part 1 shows that sl(N) web/foam homologies give obstructions to ribbon concordance, and is inspired by work of Levine and Zemke.

Part 2 uses spectral sequences to bound distance measurements between knots (alternation number and Turaev genus) and is inspired by work of Alishahi and Dowlin.

My office hours are on Wednesday, 16 June 2021. All questions are welcome!
