We extend the criterion of Kawatani and Okawa for indecomposability of the derived category of a smooth projective variety to arbitrary schemes. For relative schemes, we also give a criterion for the nonexistence of semiorthogonal decompositions that are linear over the base. These criteria are based on the base loci of the global or relative dualizing complexes.

任意方案派生类别的不可分解性
我们将 Kawatani 和 Okawa 的标准扩展到任意方案的光滑投影簇的派生类别的不可分解性。对于相关方案,我们还给出了不存在基上线性的半正交分解的准则。这些标准基于全局或相对二元化复合体的基本基因座。
