Abstract:
The work of Donaldson and Mark made the structure of the Seiberg–Witten invariant of $3$-manifolds clear. It corresponds to certain torsion type invariants counting flow lines and closed orbits of a gradient flow of a circle-valued Morse map on a $3$-manifold. In the paper, these invariants are studied by using the Morse–Novikov theory and Heegaard splitting for sutured manifolds, and detailed computations are made for knot complements.
Keywords:
oriented knot, sutured manifold, Morse map, Novikov complex, half-transversal gradients, Lefschetz zeta function.
