We construct an invariant called guts for second homology classes in irreducible 3-manifolds with toral boundary and non-degenerate Thurston norm. We prove that the guts of second homology classes in each Thurston cone are invariant under a natural condition. We show that the guts of different homology classes are related by sutured decompositions. As an application, an invariant of knot complements is given and is computed in a few interesting cases. Besides, we show that the dimension of a maximal simplex in a Kakimizu Complex is an invariant.

  1. Guts of nearly fibered knots

    math.GT 2022-08 unverdicted novelty 5.0

    Provides three models for the guts of nearly fibered knots and shows the nearly fibered condition admits a purely topological characterization independent of Floer theory.
