Higgs丛模空间的Sectional curvature渐近性

Sectional curvature asymptotics of the Higgs bundle moduli space

Jan Swoboda

摘要:

我们确定了在远离判别轨迹的黎曼曲面$Σ$上秩为$2$的Higgs丛的模空间$\mathcal M$的自然$L^2$ hyperkähler度规$G_{L^2}$的截面曲率在大Higgs场极限中的渐近行为.结果表明,他们的领导阶部分是由狄拉克型贡献的总和$Σ$,我们找到明确的表达式。

英文摘要:

We determine the asymptotic behavior in the limit of large Higgs fields of the sectional curvatures of the natural $L^2$ hyperkähler metric $G_{L^2}$ of the moduli space $\mathcal M$ of rank-$2$ Higgs bundles on a Riemann surface $Σ$ away from the discriminant locus. It is shown that their leading order part is given by a sum of Dirac type contributions on $Σ$, for which we find explicit expressions.
