Working group on odd Khovanov homology

This is the second talk in the series on constructing stable homotopy types associated with odd Khovanov homology. We will introduce the notion of 1-flow categories and explain how they can be constructed from 2-functors from the cube category to the signed Burnside category. Using these 1-flow categories, we will define two Steenrod square–like operations on odd Khovanov homology groups.
