Quadratic differentials as stability conditions
We prove that moduli spaces of meromorphic quadratic differentials with
simple zeroes on compact Riemann surfaces can be identified with spaces of
stability conditions on a class of CY3 triangulated categories defined using
quivers with potential associated to triangulated surfaces. We relate the
finite-length trajectories of such quadratic differentials to the stable
objects of the corresponding stability condition.Comment: 123 pages; 38 figures. Version 2: hypotheses in the main results
mildly weakened, to reflect improved results of Labardini-Fragoso and
coauthors. Version 3: minor changes to incorporate referees' suggestions.
