Title of Talk: Khovanov homology and positivity notions
Date: January 07, 2026
Time: 16:00:00 Hours
Venue: A-369

Abstract: In this talk, we discuss what `positivity' means in the study of links. We will examine several notions of positivity and explore how different versions of Khovanov homology—such as even, odd, and HOMFLY–PT homologies—can be used to study them. These homological techniques provide powerful methods for studying the structural and geometric properties of positive links.
