椭圆纤维化的稳定性和Fourier-Mukai变换

Stability and Fourier-Mukai transforms on elliptic fibrations

Jason Lo

摘要:

我们系统地开发Bridgeland的和Bridgeland-Maciocia的技术研究椭圆纤维化,并确定标准,确保2项复杂的傅立叶-Mukai变换下映射到无扭层。作为应用,我们构造了一个从稳定复模到椭圆三重上Gieseker稳定层模的开浸入。作为另一个应用,我们给出了Weierstrass曲面上纤维状半稳定无挠层与余维1层之间的各种1-1对应。

英文摘要:

We systematically develop Bridgeland's and Bridgeland-Maciocia's techniques for studying elliptic fibrations, and identify criteria that ensure 2-term complexes are mapped to torsion-free sheaves under a Fourier-Mukai transform. As an application, we construct an open immersion from a moduli of stable complexes to a moduli of Gieseker stable sheaves on elliptic threefolds. As another application, we give various 1-1 correspondences between fiberwise semistable torsion-free sheaves and codimension-1 sheaves on Weierstrass surfaces.
