AI 中文摘要
我们给出一个准则,用于判定Fourier–Mukai核的盒积是否能诱导出一个完全忠实函子,将其映射到对称商叠的导出范畴。这催生了许多模空间导出范畴嵌入的新例子。我们更详细地研究曲线上稳定丛模空间的情形:具体而言,我们确定了该嵌入左正交补的部分,并将已知的秩2、固定行列式的丛模空间的半正交分解,扩展到了行列式可变的丛模空间。
英文摘要
We give a criterion for the box product of a Fourier--Mukai kernel to induce a fully faithful functor to the derived category of a symmetric quotient stack. This leads to many new examples of embeddings of derived categories of moduli spaces. We study in more detail the case of the moduli space of stable bundles on a curve. Concretely, we identify pieces of the left-orthogonal complement of our embedding, and extend the known semi-orthogonal decomposition of the moduli space of bundles with rank 2 and fixed determinant to the moduli space of bundles with varying determinant.
