To study properties of knots, topologists have been using two types of
invariants: combinatorial invariants (such as knot polynomials and
Khovanov homology) and invariants inspired by gauge theory (such as Floer
homology). We will discuss some examples and then focus on a series of
Floer-theoretic invariants that are conjecturally equivalent to some known
combinatorial ones.
