I will discuss recent joint work with L. Katzarkov and M. Kontsevich (arXiv:1409.8611). Starting from a quadratic differential on a compact Riemann surface which is allowed to have zeros, poles, and certain exponential-type singularities we construct a Bridgeland stability condition with stable objects corresponding to finite geodesics. The relevant category is the partially wrapped Fukaya category of a surface, for which we give a self-contained, combinatorial definition. The proof relies on the fact that the classification of objects in these categories is a tame problem and has a nice solution in terms of immersed curves with local system.
