摘要

研究了局部环上最小自由分辨率下小子理想的渐近行为。特别地，我们证明了这些理想最终是在完全交点和gold环上的2周期的。我们还建立了在任意无限最小自由分辨率下，子点理想的稳定行为的一般结果。这些理想与迹理想和上同湮灭子有着密切的联系。在许多情况下，得到了未成年人理想所达到的稳定值的约束条件，在某些情况下，可以显式地计算出这些约束条件。

Periodicity of ideals of minors in free resolutions

We study the asymptotic behavior of the ideals of minors in minimal free resolutions over local rings. In particular, we prove that such ideals are eventually 2-periodic over complete intersections and Golod rings. We also establish general results on the stable behavior of ideals of minors in any infinite minimal free resolution. These ideals have intimate connections to trace ideals and cohomology annihilators. Constraints on the stable values attained by the ideals of minors in many situations are obtained, and they can be explicitly computed in certain cases.
