| contents | Famous work of Bridgeland and Smith shows that certain moduli spaces of quadratic differentials are isomorphic to spaces of stability conditions on particular 3-Calabi-Yau triangulated categories. This result has subsequently been generalised and extended by several authors. One facet of this correspondence is that finite-length trajectories of the quadratic differential are related to categories of semistable objects of the corresponding stability condition, which have associated Donaldson-Thomas invariants. On the other hand, computations in the physics literature suggest certain values of these invariants according to the type of trajectory. In this paper, we show that the category recently constructed by Christ, Haiden, and Qiu gives Donaldson-Thomas invariants which agree with the predictions from physics; in particular, degenerate ring domains of the quadratic differential give rise to non-zero Donaldson-Thomas invariants. In calculating all of the invariants, we obtain a novel application of string and band techniques from representation theory. |
