曲线稳定性条件

Stability conditions on curves

Emanuele Macri

摘要:

我们研究了三角范畴上Bridgeland-Douglas稳定性条件的一些例子。从一个方面给出了正亏格光滑射影曲线的稳定流形的完整刻画。另一方面,我们研究了由例外集合生成的三角范畴的稳定性条件。在投影线的情况下,这导致了稳定流形的连通性和单连通性。

英文摘要:

We study some examples of Bridgeland-Douglas stability conditions on triangulated categories. From one side we give a complete description of the stability manifolds for smooth projective curves of positive genus. From the other side we study stability conditions on triangulated categories generated by an exceptional collection. In the case of the projective line this leads to the connectedness and simply-connectedness of the stability manifold.
