导出范畴中的稳定对理论产生了3重曲线的枚举几何。我们用加权盒计数的方法计算环面3重上稳定对的等变顶点。在复曲面Calabi-Yau情形中,结果简化为一种新形式的纯盒计数。与DT顶点的拓扑等价预示了显著的恒等式。在复曲面簇的稳定对理论中,等变顶点支配准素插入。我们还考虑了稳定对的下降顶点和猜想的下降理论的完全合理性。14 N35; 14 M25,14 D20,14 J30
The theory of stable pairs in the derived category yields an enumerative geometry of curves in 3‐folds. We evaluate the equivariant vertex for stable pairs on toric 3‐folds in terms of weighted box counting. In the toric Calabi‐Yau case, the result simplifies to a new form of pure box counting. The conjectural equivalence with the DT vertex predicts remarkable identities. The equivariant vertex governs primary insertions in the theory of stable pairs for toric varieties. We consider also the descendent vertex and conjecture the complete rationality of the descendent theory for stable pairs. 14N35; 14M25, 14D20, 14J30
