论文摘要
我们提供了所有图表的表征，其奇偶校验二线边缘理想具有纯粹的分辨率。特别是，我们表明，当且仅当相应的图是完整的两部分图或路径和奇数循环的不连接时，且仅当相应的图是奇迹二项式边缘理想的最小自由分辨率是纯粹的。
We provide a characterisation of all graphs whose parity binomial edge ideals have pure resolutions. In particular, we show that the minimal free resolution of a parity binomial edge ideal is pure if and only if the corresponding graph is a complete bipartite graph, or a disjoint union of paths and odd cycles.
