乘法希格斯丛与对合

Multiplicative Higgs bundles and involutions

Guillermo Gallego, Oscar Garcia-Prada

AI总结:

本文将曲线上的乘法$G$-希格斯丛理论推广到带对合$θ$的约化代数群对$(G,θ)$情形,引入取值于相关对称簇或其等变嵌入的对应丛概念,并研究其作为$θ$诱导的模空间对合的不动点的性质。

摘要:

本文将曲线上的乘法$G$-希格斯丛理论推广到对$(G,θ)$的情形,其中$G$是约化代数群,$θ$是$G$的一个对合。该推广涉及取值于与$θ$相关的对称簇或其等变嵌入的乘法希格斯丛概念。我们还研究了这些对象如何作为乘法$G$-希格斯丛模空间的对合不动点出现,这些对合由对合$θ$诱导。

英文摘要:

In this paper we generalize the theory of multiplicative $G$-Higgs bundles over a curve to pairs $(G,θ)$, where $G$ is a reductive algebraic group and $θ$ is an involution of $G$. This generalization involves the notion of a multiplicative Higgs bundle taking values in a symmetric variety associated to $θ$, or in an equivariant embedding of it. We also study how these objects appear as fixed points of involutions of the moduli space of multiplicative $G$-Higgs bundles, induced by the involution $θ$.
