AI 中文摘要
我们证明了当秩与度互素时,典型$\mathrm{SL}_n$ Hitchin系统的perverse滤过具有乘法性。在偶次扭曲Hitchin系统的椭圆轨迹上,我们将紧化Prym的Fourier投影子与内窥对应进行比较。然后利用变体上同调的平方零性质及抛物Higgs模约化,推广至全典型模空间。
英文摘要
We prove that the perverse filtration of the canonical $\mathrm{SL}_n$ Hitchin system is multiplicative when the rank and degree are coprime. Over the elliptic locus of an even-degree twisted Hitchin system, we compare the Fourier projectors for compactified Pryms with the endoscopic correspondence. We then use the square-zero property of the variant cohomology and a parabolic Higgs moduli reduction to pass to the full canonical moduli space.
