本文针对带有碰撞标记的单纯稳定曲线,通过分解约化态射得到重构公式,推导修正后的Virasoro递推关系,并将有限支撑理论封装于Fock空间,拓展了Witten-Kontsevich势的相关研究。

中文摘要 AI 辅助

我们研究单纯稳定曲线模空间上的后代积分。对于每个有限碰撞复形,我们将约化态射分解为基本壁跨越,并利用普通Witten-Kontsevich关联函数得到重构公式。我们用该公式推导修正后的Virasoro递推关系,随后将所有有限支撑理论封装在完备不交支撑Fock空间中,其中扩展势是Witten-Kontsevich势的累积量平移。

英文摘要

We study descendant integrals on moduli stacks of simplicially stable curves. For each finite collision complex, we factor the reduction morphism into elementary wall crossings and obtain a reconstruction formula in terms of ordinary Witten-Kontsevich correlators. We use the formula to derive corrected Virasoro recursions. We then package all finite-support theories in a completed disjoint-support Fock space, where the extended potential is a cumulant translate of the Witten-Kontsevich potential.
