AI总结:

本文证明了toric对的logarithmic GW/PT猜想,首次验证了当∂Y奇异时的猜想,并在∂Y非空时给出证明,同时证明了PT系列为Laurent多项式,验证了logarithmic DT/PT猜想。

摘要:

我们证明了对于由 toric 三维流形 Y 和任意 torus 不变除子 ∂Y 构成的对 (Y|∂Y),logarithmic Gromov-Witten 理论与 logarithmic Donaldson/Pandharipande-Thomas 理论之间的猜想对应关系,其中主要插入物为 primary insertions。结果是当 ∂Y 是奇异的,即“完全 logarithmic”设置时,该猜想的首次验证,以及当 ∂Y 非空时,该猜想的首次证明。当 ∂Y 为空时,我们得到了已知 toric 对应关系的新证明,但我们的方法也导致了更强的结论。特别是,我们证明了 PT 系列在足够正性的情况下是一个 Laurent 多项式,并证明了 2008 年 Oblomkov, Okounkov, Pandharipande 和第一作者提出的关于 capped vertex 是 Laurent 多项式的猜想。方法还验证了 toric 三维对的 logarithmic DT/PT 猜想。利用 logarithmic 理论的约束,toric 对的完整评估由单个计算确定——P^3 的度 1 系列。

英文摘要:

We prove the conjectural correspondence between logarithmic Gromov-Witten theory and logarithmic Donaldson/Pandharipande-Thomas theory for pairs $(Y|\partial Y)$ consisting of a toric threefold $Y$ and any torus invariant divisor $\partial Y$, with primary insertions. The results are the first verifications of this conjecture when $\partial Y$ is singular, i.e., the ``fully logarithmic'' setting, and the first proof of the equivariant toric correspondence for pairs when $\partial Y$ is nonempty. When $\partial Y$ is empty, we get a new proof of the known toric correspondence, but our methods also lead to stronger conclusions. In particular, we show the PT series is a Laurent polynomial in the presence of sufficient positivity and prove a 2008 conjecture of Oblomkov, Okounkov, Pandharipande, and the first author stating the capped vertex is a Laurent polynomial. The methods also verify the logarithmic DT/PT conjecture for toric threefold pairs. Using the constraints of the logarithmic theory, the complete evaluation of toric pairs is determined by a single calculation -- the degree $1$ series of $\mathbb{P}^3$.
