我们推广的Horrocks单子的理论,ACM品种,并使用推广建立一个上同调性质的线性和Steiner丛的射影空间和二次超曲面。我们还刻画了图4中直线的Grassmannian G(1,4)上的Steiner丛.最后,我们研究了丛在ACM簇上的线性分解,刻画了二次超曲面上的线性同调维数。
We generalize the theory of Horrocks monads to ACM varieties, and use the generalization to establish a cohomological characterization of linear and Steiner bundles on projective space and on quadric hypersurfaces. We also characterize Steiner bundles on the Grassmannian G(1, 4) of lines in ℙ4. Finally, we study linear resolutions of bundles on ACM varieties, and characterize linear homological dimension on quadric hypersurfaces.
