| Abstract: | Recently, Bridgeland and Smith constructed stability conditions on some $3$-Calabi-Yau categories from meromorphic quadratic differentials with simple zeros. In this talk, generalizing their results to higher dimensional Calabi-Yau categories, we describe the space of stability conditions on $N$-Calabi-Yau categories associated to $A_n$-quivers as the universal cover of the space of polynomials of degree n+1 with simple zeros. In particular, central charges of stability conditions on $N$-Calabi-Yau categories are constructed as the periods of quadratic differentials. |
