Shifted Partial Quadratics, their Pushforwards, and Signature Invariants for Tangles (Dror Bar-Natan, Toronto)

01.12.2023 16:00 – 17:00

Following a general discussion of the computation of zombians
of unfinished columbaria (with examples), I will tell you about my
recent joint work with Jessica Liu on what we feel is the "textbook"
extension of knot signatures to tangles, which for unknown reasons, is
not in any of the textbooks that we know.
