HTLW01 - Winter school workshop

By endowing the annular Khovanov-Lee complex with the structure of a bifiltered complex, we define a family of annular Rasmussen invariants that gives information both about the positivity of braids viewed as mapping classes and the complexity of braided surfaces bounded by their closures (j. work with T. Licata and S. Wehrli).
