在本文中,我们考虑如何的Bezrukavnikov和Kaledin的方法来理解范畴的相干层辛决议可以适用于库仑分支介绍的Braverman,Finkelberg和Nakajima。特别是,我们构建倾斜发电机解决库仑分支,并给出明确的coherent介绍这些品种的相干层的类别,与自然双模描述的跨壁函子。
In this paper, we consider how the approach of Bezrukavnikov and Kaledin to understanding the categories of coherent sheaves on symplectic resolutions can be applied to the Coulomb branches introduced by Braverman, Finkelberg and Nakajima. In particular, we construct tilting generators on resolved Coulomb branches, and give explicit quiver presentations of categories of coherent sheaves on these varieties, with the wall-crossing functors described by natural bimodules.
