Computations of instanton knot Floer homology with local coefficients

  • Speaker: Tom Mrowka
  • Time: 11:20-12:20
  • Abstract: This talk will discuss some motivating problems for developing a version of instanton knot Floer homology with local coefficients. These Floer homology groups are modules over Laurent polynomial rings. Though more complicated than the vanilla version they turn out to be easier to compute. We’ll describe some of computations of these modules. One emphasis will be on the product case of a trivial n-strand braid in S1xS2, generalizing work of Ethan Street. This is joint work with Peter Kronheimer.
